As a top expert in titanium alloy in China, Cao Dongming attaches great importance to the achievements in the field of titanium alloy, because he knows how widely used titanium alloy is in the aviation field.

Cao Dongming is a researcher at the Institute of Aeronautical Materials, a technical expert affiliated with the Aviation Group, who has participated in the manufacture of advanced fighters and understands that one of the general directions of fighter development is to replace heavier alloy materials with titanium alloy materials.

For example, steel.

No matter what kind of steel, the density is very high, and the density of titanium alloy is only 60 or 70 percent of steel, and the hardness is not inferior to steel, so it is naturally the preferred material to replace steel.

In the aviation field, there are two directions for the research and development of titanium alloys, one is to reduce costs, and the other is to manufacture titanium alloys for various purposes to meet the needs of various components of aircraft.

Most of the components on the aircraft need alloy materials, including shells, engines, shafts, landing gear, etc., if all are replaced with titanium alloy to manufacture, to achieve the same performance, the weight can be lighter by more than 20 or 30 percent, not only fast speed, high load-bearing, but also more flexible.

If you want to meet the needs of various parts of the aircraft, you need to manufacture various types of titanium alloys, so you need to have enough knowledge about titanium alloy manufacturing.

So how can you increase your understanding?

This calls for more materials science research projects similar to 'super-compressive alloy materials'.

The research and development of β-type titanium alloy to increase strength is a major research in the field of titanium alloys, and it is precisely because of its importance that the National Natural Science Foundation of China will support it.

The increase in strength of β-type titanium alloy is not like solving a single problem, because there are many influencing factors, and it can be said that there is no definite direction, and each study can only be used as a reference.

However, if a research can produce an ultra-high-strength titanium alloy using conventional means, it means that it is 'very close' to the right direction, and it will become very valuable.

The current production of titanium alloys with a tensile strength of 1560 megapascals belongs to the kind of research that has achieved very significant results.

Because of this, Cao Dongming attaches great importance to it.

After he and Peng Hui learned about the R&D process, they went directly to the data analysis office, and he was very interested in the analysis of how Wang Hao did it.

This may be able to be applied to other research in the field of titanium alloys.

After arriving at the data analysis office, there was no matter for Peng Hui, and Wan Yiming, who was in charge of data analysis, explained to Cao Dongming.

Wan Yiming's data analysis for Wang Hao has been studied for a long time, and the first 80% of the content has been thoroughly understood.

He explained it very thoroughly.

Cao Dongming also kept listening and nodding, and then understood the analysis process, until it was time to explain the calculation and analysis, and Wan Yiming stopped talking.

"Go on?" Cao Dongming raised his head and was a little puzzled.

Wan Yiming smiled awkwardly and said, "Professor Cao, I don't fully understand the last part. ”

"Huh?"

This answer was quite unexpected.

Cao Dongming is not from the metal laboratory, so he can't say anything directly, so he nodded and said, "Then so be it, you are busy with yours first." ”

"Good~~"

Wan Yiming felt very embarrassed and hurriedly walked away to continue to analyze and understand.

Peng Hui was walking to the side.

Cao Dongming couldn't help but whisper to Peng Hui, "The level of this material analyst in your laboratory is not very good", he kept shaking his head as he spoke.

"yes!"

Peng Hui nodded vigorously in agreement.

He did feel that Wan Yiming's level was very poor, and it was not as helpful as Shi Guifang, who did data calculation, to do data analysis, but he still knew that every laboratory must have data analysis personnel.

Wan Yiming still has some achievements in the theory of data mining, and it is not easy to find the same level.

Cao Dongming sighed with emotion, and then began to look seriously, he is already in his fifties, and he knows a lot about the research of titanium alloy projects, even if it is complex data analysis, he can also know the method.

Ten minutes passed......

Twenty minutes passed......

Cao Dongming felt that he was probably in a bad mental state, and rarely asked his doctoral students to help make a cup of coffee, he drank coffee very rarely, mainly related to his living habits, but now he must drink a cup of coffee to refresh himself.

Then, another hour passed.

Cao Dongming sat on the chair expressionlessly, staring at the pile of code on the computer and the annotations next to it, looking left and right to think.

Eventually, he stood up and went to Peng Hui's office.

Peng Hui hurriedly stood up and asked, "Professor Cao, how are you looking?" ”

"Ahem."

Cao Dongming touched the corners of his mouth and said, "I thought about it just now, it's better for a special person to study data analysis." ”

"I'm here to understand the implementation process."

He nodded his head very seriously, as if he thought so in his heart.

Peng Hui agreed, "yes, I think so too, so I never meddle in those complex data problems. ”

Cao Dongming continued to agree, "That's it. The most important thing for us to lead a team to do a project is to grasp the general direction and let everyone in the team perform their own duties......"

……

The other side.

Wang Hao continued his data analysis work.

Three sessions a week brought in 31 points of inspiration, which allowed him to break through 100 points again, and then he had a new method of analysis for some data that had not been analyzed before.

Once you have an idea, take notes and do your research to complete the task as soon as possible.

He spent the whole day working on the new code, and then went to the computer lab to borrow a server to do the calculations.

This time it was less computational than the last time, but he still applied for a grant of 5,000 yuan to pay for the use of the server.

Chen Qinghua can give a hundred likes to his approach, he feels that Wang Hao is very principled in doing things, using the equipment of the computer laboratory to calculate the research content of other teams, normally speaking, he does have to pay a certain fee.

The little old man had a lot of admiration in his heart, and he still had to say hello verbally, showing that he was forced to accept it out of reluctance.

This practice can be described in two words as 'hypocrisy'.

Of course, similar things can also be described by etiquette, the cultural tradition of the Chinese people is to be modest and polite, and if there are any ideas, they will show them directly, and there will be some impropriety.

Wang Hao didn't think about it so much, he insisted on his principle, he must give the money to the computer lab and use their server for computing, that is, it is used in the bright future.

It will make the heart feel very comfortable.

When all the code was entered into the computer, after the official start of the calculation, Wang Hao also exhaled lightly, although the calculation results have not yet come out, but after the calculation is completed, and then summarize, the analysis can be completed.

The study was finally completed, and he was looking forward to the fact that the A-level difficulty study would add an additional thousand Teaching Coins.

The last research on the Mersenne prime algorithm also brought a thousand teaching coins.

[Teaching coin: 5597.] 】

If you can add another 1,000 teaching coins, you will be 2-thirds away from the goal of 10,000.

"There is only a third left, and the march has gone so many ......"

"But keep walking!"

……

On the same day, the expert review team temporarily formed by the Department of Materials Science came to the metal laboratory of Xijing Jiaotong University.

This expert review team is composed of seven member experts, including Cao Dongming, who arrived first, and other experts in the field of metal alloys from various universities and institutions.

They didn't want to come so early, and the scheduled time was next weekend, but Cao Dongming came first, and they could only follow.

Everyone in the expert review team is interested in the research of the metal laboratory, and after coming, they are as concerned about the research problem as Cao Dongming, and after combing the entire research process, they find that there is no problem, so they plan to take the manufactured alloy back for testing.

"This should be the end result, right? Your lab is ready to settle the bill. ”

A leading expert said.

He is Li Jiping, 61 years old, a top expert in non-ferrous metals, a professor at Capital University, an academician of the Academy of Sciences, and the leader of the expert review team.

The expert review team came to do the audit, and found that there was no problem with the research, so they could go back to the final product for testing, and at the same time wait for the metal laboratory to make a detailed report.

After a series of approvals and stamps, the project can be settled.

The follow-up closure has nothing to do with the expert review team.

When Peng Hui heard Li Jiping's words, he hesitated, "Academician Li, we haven't planned to settle the project yet?" ”

"Why?" Li Jiping asked incomprehensibly.

Everyone else has seen it.

Peng Hui is also a veteran material expert, but there are several people in the expert review team, and each of them is no worse than him alone, and a group of people look at it together, he is still a little pressured, but he still insists, "Professor Wang Hao's analysis work is not over yet." He told me the day before yesterday that the next report would come out today or tomorrow. I'd like to do another experiment based on his analysis. ”

"One analysis shouldn't matter, right?" Li Jiping frowned, in his understanding, the data analysis personnel of materials research is a position that belongs to the new development.

If you go back 20 or 30 years, there was no data analyst position in the materials research team.

The study of materials is to constantly do experiments, if the temperature is not good, raise the temperature, and find new methods if the melting is uneven, what is the use of sitting there and analyzing the data?

The experts also heard about the role of Wang Hao's analysis in promoting the results, but what they heard and what they saw with their own eyes were completely different.

They do not deny that the analysis is effective, but at the same time feel that the luck component is high.

Based on their past R&D experience, one or two data analysis and one or two experiments are not of much significance at all.

Cao Dongming thinks that Wang Hao's analysis is meaningful, and the methods used in it have a certain value, but there is no way to deny other people's opinions, because he led the team to do a lot of research, and the experimental data analysts in the team, the results of the analysis cannot be said to be completely unhelpful, but the effect is also very limited.

This is the current state of much materials research.

If we can advance step by step and develop the materials with the desired effect through scientific analysis, the domestic high-end material field will not be stuck by foreign countries for a long time.

Peng Hui and the experts had the same understanding before, but he personally experienced the research process, stuck in the problem for a few months, and was solved by Wang Hao in a few words, and then made an analysis and made an alloy with a tensile strength of 1560 megapascals.

Now it's useless to say analytics?

Those complex analyses are useless and useless, I dare not be 100% sure, but listening to Wang Hao's must be right.

That's what Peng Hui thinks.

He shook his head very resolutely, and even scolded Li Jiping, "I still think that we have to wait for the results of Professor Wang Hao's analysis, and I have to do another experiment." Moreover, we only reported the results, and we didn't say that we wanted to settle the project. ”

The expert reviewers have nothing to say about this sentence.

Materials science does not pay attention to the R&D results of the metal laboratory, so it sets up an expert review team to come and take a look, and it is not for them to accept the results.

It's just that a few of them want to bring the manufactured alloy back for testing, so they don't have to go again, so they suggest that they directly do the results settlement.

A few people in the expert review team, you look at me, I look at you, I still think that doing one more experiment is a waste of time, but there is no way to refute what Peng Hui said.

In the end, Cao Dongming stood up, "That's it, doesn't it mean that the results will be available today or tomorrow?" Or just wait another day or two, anyway, I also came to Xijing, this is a city with a strong historical heritage, and you can take the opportunity to go around. ”

This sentence immediately eased the atmosphere.

There are steps on both sides, and the atmosphere is much more relaxed.

……

After dealing with the expert review team, Peng Hui also felt very pressured.

Now he chooses to believe Wang Hao, believing that after the analysis results, he will definitely be able to manufacture titanium alloys with higher strength.

Several experts disagreed, but relented and decided to stay two more days.

If a stronger alloy can be made after two days, it will naturally be a big face-gain, and the expert judges will have nothing to say, and even be amazed by it.

Otherwise, you will lose a big face.

The people in the expert review team are not professional in the review work, they are all from universities and institutions, and they all have their own jobs, and they are all very busy, just like Cao Dongming has five projects to do, and he can be very busy when he goes back.

Two days sounds very short, but it can be a little depressing to delay it for two days.

Peng Hui also understands the feelings of several expert judges, but he still has to insist because of his incomparable trust in Wang Hao.

In other words, the metal laboratory has great trust in Wang Hao.

Peng Hui called Wang Hao and asked, knowing that the results would come out immediately, so he simply said, "Otherwise, Professor Wang Hao, can you come here?" Regardless of whether the experiment has improved or not, the data analysis work has ended. I definitely don't have enough skills on my own, I can't do anything more, and the project can be settled. ”

"It's just right for you to come here, the experiment before the settlement, and the review of the materials department, you are the one who has made the greatest contribution to the research, and it will be ...... to come."

"Wow, wow~~"

Peng Hui said a lot in a row, that is, he hoped that Wang Hao could come to visit, one was the person who made the greatest contribution before the project was settled, and it was natural to come over.

The second is that he is under pressure and hopes that Wang Hao will come over and explain the results of the analysis directly, instead of submitting it in the form of a report.

Wang Hao thought about it for a while, thinking that there was nothing to do on the weekend, so he simply said, "It's okay to go once, but it can't be too long, at most until Monday, and Tuesday's class can't be delayed." ”

Attending classes is much more important than participating in experiments.

Peng Hui was immediately relieved, and hurriedly said, "I'll let people book air tickets and hotels for you!" ”

"Tomorrow, it's decided!"
