The excitement of Peng Hui, Shi Guifang, Wan Yiming and others is justified.

The production of a new ratio of titanium alloy with a tensile strength of 1,400 megapascals, and a relatively simplified manufacturing process, is indeed an exciting achievement, and it can be said that the expected goals of the project research have been achieved.

Titanium alloy is a material field that attaches great importance to the world, and there are many institutions that carry out related research, and there are many types of titanium alloys.

From the internal matrix structure, titanium alloys can be divided into α alloys, β alloys and (α+β) alloys.

In China, TA, TC, TB is expressed, each of which has several or more than a dozen models, in other words, there are more than 20 kinds of standard titanium alloy materials sold on the market.

There are many types of titanium alloys, which are mainly related to the application direction.

In the application field of titanium alloy, it is not that the higher the strength, the better, in fact, if it is only a comparative strength, the strength of the domestic production of special steel, the strength can exceed 2000 megapascals, which can be said to be the international leading, but the steel does not have plasticity, processing, welding is a big problem, and the application difficulty will be very high.

The biggest advantage of titanium alloy over special steel is that it is light, because the density is relatively low, and the weight is only about 60% of steel under the same volume.

Because of the low density, titanium alloy is widely used in the aviation field, and many parts of aviation aircraft and military aircraft will be manufactured with titanium alloy.

However, the disadvantages of titanium alloy are also obvious, and the biggest disadvantage is that it is expensive.

Titanium alloys are expensive not because of the low titanium content, but because the 'titanium' element is very easy to react with many other elements at high temperatures, and it will be very troublesome to get titanium out of other impurities, and it is often necessary to operate in an inert gas or vacuum environment when it is finally formed.

Such a complex operation that comes and goes is destined to make the price of titanium alloy materials very expensive.

The laboratory uses refined titanium to make titanium alloys, and the operation at high temperature also needs to isolate the air, the process seems simple, but in fact, just because it is a laboratory operation, the manufacture is only a small piece, and some steps that need to isolate the air are carried out in professional equipment.

The second disadvantage of titanium alloy is that it is difficult to process and weld.

There is an example that Amriken is known as the 'Immortal Blackbird', a fighter that can fly at a maximum speed of Mach 3, and is known as the fastest aircraft ever built, and the reason why he can fly so fast is because he uses 30 tons of titanium alloy, most of which are made of titanium alloy.

However, there is a very obvious drawback of this aircraft, which is the oil leakage.

American tried all kinds of things to solve the problem, because at that time they had not yet mastered the perfect welding technology of titanium alloys.

This is enough to show how difficult it is to process and weld titanium alloys.

However, at present, China has mastered the high-end 3D titanium alloy printing technology, which can directly shape the corresponding parts with 3D printing, and skip the welding process.

This is off-topic.

The project of the metal laboratory is the research of ultra-compressive titanium alloy materials, and the purpose of their research is not application, but specifically to study how to improve the strength of titanium alloys made at 'normal costs'.

Internationally, the maximum strength of titanium alloy can reach 1700 megapascals, but it is manufactured by abnormal means, and it cannot be popularized at all.

In the case of conventional means to manufacture, the compressive strength of the final product can exceed 1400 megapascals, which is already a very high data.

This project belongs to 'material science research', not 'material application research', and the titanium alloy manufactured is not to be applied to make products, but to study the conventional means to manufacture titanium alloy, and what process can improve its strength.

This is a very valuable reference for the application research of titanium alloy materials.

Other research teams that do targeted applications can improve the strength of the corresponding titanium alloy according to their process reference.

In other words, the manufacturing process is more important than the result.

This is also the reason why Ma Wenjun is worried that other teams will have results in their research.

If the research of other teams is fruitful, there will definitely be many experts who specialize in analyzing the manufacturing process and various data, and their alloy laboratories have done the same project, even if they are suspended in the middle, the data related to the experiment have already been reported.

Comparing the two, there is a high probability that the problem will be found.

……

After the experiment was successful, Peng Hui and Shi Guifang talked a lot around Wang Hao, but he still didn't quite understand the excitement of the metal laboratory.

Because the final product is made, there is no innovation, and there is no qualitative improvement in performance.

Isn't scientific research about qualitative breakthroughs? Isn't it about solving the problems that aren't being solved?

Tens of millions of dollars have been spent and small progress has been made, and it is really difficult to find exciting points.

Wang Hao went back with a little incomprehension, maybe there was another reason why he was not excited, because he didn't participate in the project at all, he just blessed his soul and made a small suggestion.

When he was on the plane, Wang Hao began to count the harvest.

This trip to Xijing Jiaotong University, the inspiration value is still very large, and the corresponding task inspiration value has increased to '79' points, which shows that the experimental data has been very understood.

This value has almost reached the peak of understanding 'experimental data', and even if you study experimental data, it is very difficult to improve a few points.

When there is enough foundation, what is missing is analytical inspiration, which requires other means to obtain it.

For example, research on data analysis methods, or feedback through teaching.

The latter is the easiest to achieve.

Wang Hao misses the students a little, and he can't wait to go to a class, hoping to increase his inspiration points by more than 100 points.

After returning to Xihai City, he went home to rest for a day.

The next morning, Wang Hao came to school in good spirits, and when the time came, he went to class with 100% enthusiasm.

Probability Theory and Mathematical Statistics.

This course has entered the final stage, and when it enters the final stage, the knowledge difficulty has also been raised to the highest level, and some content involves knowledge that is not required at the undergraduate level.

But Wang Hao's explanation is still very detailed, and I hope that more students can understand and grasp it, and of course, at the same time, it can also give back more inspiration values.

Teaching, giving back, mutual benefit!

After lunch, he immediately returned to his office in the complex, and after a class, he brought a 20-point inspiration boost.

For A-level R&D tasks, getting 20 inspiration points in one class can be said to be quite high.

This value confirms Wang Hao's previous judgment, and only with sufficient foundation and understanding of experimental data can we get more inspiration values.

After opening the quest system, he found that the embarrassing thing was that the quest's inspiration value reached 99 points.

"It's just a little bit!"

The inspiration value is only 1 point, but not just the data, he feels that he already knows an analysis method, but he is only one step away, but he can't get through, as if solving a math problem, knowing the general idea of solving the problem, but there is a problem at the beginning, and he doesn't know where to start to solve it.

Wang Hao could only continue to analyze the data, and after studying for more than an hour there was no result, and he somewhat understood why Zhang Zhiqiang often scratched his scalp.

Zhang Zhiqiang happened to look over and asked, "What's the matter, Wang Hao?" ”

Wang Hao sighed, "There is a problem that I can't think of. ”

"Oh."

Zhang Zhiqiang agreed, turned his head and continued to do his own thing.

Wang Hao continued to wrestle with the problem.

Zhu Ping laughed out loud when she saw it, she pointed at Zhang Zhiqiang and asked, "You guys are really interesting, shouldn't you ask, what's the problem?" ”

Zhang Zhiqiang immediately shook his head, "Wang Hao's problem that can't be solved, I listened to it in vain." ”

Zhu Ping was stunned for a moment when she heard this, nodded with deep sympathy, and found that Wang Hao looked at her, and immediately sat back in her position, turned her head and pretended to read a book seriously, as if to say, 'Don't ask me', 'Don't ask me'.

She even plugged her ears with her hands.

Luo Dayong broke away from the state of 'thinking about life', and reminded him with the corners of his mouth, "No need to do this." Don't worry, Wang Hao won't ask you. ”

Zhu Ping's face suddenly darkened, and she stared at Luo Dayong through gritted teeth.

Wang Hao saw this scene and 'burst out laughing'.

The daily life in the office is still very funny, I always feel that Luo Dayong is a comedian, every time he speaks, he can always grasp the key point, and it directly hits Zhu Ping's heart.

Hit, heart?

Wang Hao thought about it and suddenly frowned, and the next moment the system prompted--

[Task 1, inspiration +1.] 】

[Inspiration value: 100.] 】

I see!

When a problem was figured out, everything suddenly became clear, and he immediately opened the computer file and started to record it.

This is a voice suddenly coming from the door, "Wang Hao, excuse me?" ”

Wang Hao looked up and saw that it was Zhou Jianchun, the head of the department, and said, "Director Zhou, please come in." ”

Zhou Jianchun entered the office and asked directly, "Wang Hao, I met Zeng Guangxiang from the graduate school downstairs just now, and he asked me to help ask, are you going to take graduate students next year?" ”

Wang Hao suddenly realized that the graduate student enrollment work was about to begin, and the tutor and the students must report in advance.

He asked, "How many students can you take?" ”

"You're really bringing it!" Zhou Jianchun said with some surprise, "I just came to help ask, the general master's supervisor is two to four students, you are the first year, I still suggest that you take fewer students, it is best not to bring them, mathematics research does not need students to help anything, focus more on research." ”

Zhou Jianchun was indeed a little surprised, because Wang Hao's mathematical research achievements were outstanding, and he must have put most of his energy on research, he just came over to help ask, and felt that Wang Hao should not take students.

Wang Hao is indeed very serious about teaching, but teaching is to give lectures to many people, and there is also a fixed time, so it is different to take graduate students, to care about the learning progress of graduate students, to care about graduate students' papers, and so on, it will definitely consume a lot of energy.

Wang Hao said very firmly, "I have already thought about it, I must bring students, since it is usually two to four, then I will bring four, this will be reported, right?" ”

Zhou Jianchun nodded in disunderstanding, and then said, "I'll help you talk to the graduate school, and they will deal with it." ”

"Okay."

Zhou Jianchun asked Wang Hao and left, he still felt very puzzled, and after thinking about it for a long time, he didn't think of any benefit from taking a graduate student.

For other professors, taking students is the same as teaching, and having students can help with experiments and so on, which is helpful for their own research, and bringing more students is also helpful for job title rating.

None of this has anything to do with Wang Hao.

Because he has already achieved great results, he does not need to worry about the problem of job title rating at all, and he is doing mathematical theory research, and the students will definitely not be able to help.

"No good, huh?" Zhou Jianchun thought carefully for a long time and couldn't come up with a reason, so he could only attribute it to Wang Hao, who attaches great importance to teaching, and has a high consciousness of his own teaching work.

This is also the evaluation of Wang Hao by many people in the school.

……

After talking to Zhou Jianchun and knowing that the graduate school would deal with the problem, he then put things behind him and continued to focus on his work.

He has already sorted out the clues, found a way to analyze the data, and after memorizing the contents, he immediately began to write relevant programs and use programs to analyze the relevant data.

At the same time.

The Metals Laboratory of Xijing Jiaotong University has submitted a report on the results of the project.

Because it is a very important fund project, after it was submitted, experts came to check it and found that they had used conventional means to manufacture a titanium alloy with 1400 compressive strength, and they were immediately very surprised.

"This Peng Hui, it's really okay, you can complete the research with such a little funding."

"I guess the funds haven't been used up yet, right? I've been following the progress of this project, and I still have more than a third of the project left. ”

"Yes, yes, the results are outstanding, it seems that the settlement is not far away."

After a brief look at the results report, several experts felt a little surprised, because few people were optimistic about the initial approval of the project, and the funding for the project of the Science Foundation was limited, even if there was a certain level of research and development, with the support of limited funds, it was difficult to complete the research.

It was now unexpected, and they began to take a hard look at the report that had been submitted.

An expert was looking at it seriously, and suddenly said in surprise, "In your personnel list, there is a special data analyst, Wang Hao of Xihai University?" ”

"This Wang Hao, is it the one who was dismissed by Donggang? That math genius who is always in the news? ”

"Really!"

"There should be no second Wang Hao in Xihai University, a specially appointed data analyst, and his name is very high, ranking fourth, which is higher than a researcher in their laboratory."

"It seems that Wang Hao's contribution is very great, and Peng Hui also values him, otherwise it would be impossible to be so ......"

The results report of major projects will submit a list of people who have contributed to the results, and the major projects with a fund of 15 million yuan, because there are many people involved, the list can list more than a dozen or twenty.

Similar projects generally only look at the first few names, and the rest are just ordinary participants and it doesn't matter.

Wang Hao's name is ranked fourth, which is enough to show the importance of the results.

When several experts were studying the results report, Xijing Jiaotong University also issued a special announcement, the difference is that it only shows that the project of the metal laboratory has achieved the expected goals.

This kind of announcement has almost no impact to speak of, and even the people of the school are not interested in taking a look.

However, someone noticed.

Donggang University, Laboratory of Alloy Materials.

Ma Wenjun has been paying attention to the dynamics of the New Metal Materials Technology Research Institute and the Aviation Materials Institute.

Although his judgment is the same as Chen Jianlin's, he believes that the Institute of Aeronautical Materials has delayed the research, and the metal laboratory has limited funds, so there is no way to make results, but it is related to its own problems, as long as there is a slight possibility, special attention needs to be paid to.

When he saw the announcement issued by Xijing Jiaotong University, Ma Wenjun suddenly felt incredible, and he panicked to the extreme, and he immediately found Chen Jianlin.

After Chen Jianlin heard Ma Wenjun's words, he was also a little flustered, he quickly checked the news, and then picked up the phone to ask, and also knew the specific situation of the results.

"Peng Hui's team has developed conventional means to manufacture titanium alloys with a tensile strength of 1,400 megapascals."

"This parameter ...... OK! ”

Chen Jianlin exhaled lightly when he knew the result.

The tensile strength of the world's top TB titanium alloy can exceed 1200 megapascals, and some even exceed 1400 megapascals.

This data is not out of the 'conventional' range, and even if it is studied, it does not tell the question exactly.

There are many factors that affect the strength of titanium alloys, including element ratio, manufacturing process, technical means, removing impurities, and making the purity of titanium high enough is also one of the important means.

R&D results in the 'conventional' range, the manufacturing process does not necessarily tend to be standard, and it may be just 'lucky'.

It's like a group of people running in a clueless race where they don't know which direction is right, but only one is the right one.

When the running time is up, you can only know how far you will move in the right direction.

Some people ran 100 meters in one minute, the same in one minute, and some people ran 150 meters.

This is a normal range, and there is no way to rely on the distance traveled to determine the correct direction.

However, if someone runs 200 or 300 meters in a minute, to some extent, you can determine the direction in which he is running, and he is very close to the right direction.

It is also possible that the metal laboratory has made a titanium alloy with a tensile strength of 1400 megapascals by conventional means, but it is not certain that the research is the right direction.

Naturally, the comparison of experimental data does not fully explain the problem.

However, if a titanium alloy with a tensile strength of 1500 megapascals, 1600 megapascals, or even higher is manufactured, the situation is completely different.

"Peng Hui, he really has some ability, I underestimated him."

Chen Jianlin sighed with emotion and continued, "Professor Ma, at least we don't have to worry about the metal laboratory anymore, they have submitted the results, and the project is almost over, so we can rest assured." ”

Ma Wenjun's heart was also put back, and he suddenly felt relaxed all over, and asked, "How is Professor Zhou?" ”

"Xiaolong."

Chen Jianlin sighed, shook his head and said, "Don't worry about this, I've already told him, let him go home and rest for a while, wait for half a year or a year, and rearrange a job for him." ”

"Donggang University will definitely not come back, but you can go to other universities to become a teaching position. Wang Hao's kid can go to Xihai University, and I still have this face. ”
