After determining that the system could parse smaller units, Chen Nian immediately realized a serious problem:

The speed of source point acquisition is simply too slow.

At the current rate, just a mostly known titanium alloy material would cost 0.1 source points.

Although it doesn't seem like much, it's also the amount he can brush up in three days.

If you want to make an F-22, how much time will it take?

Even if it's just solving the most critical problems, it doesn't add up to a small number.

The final result may not be much faster than the country's self-development, that is, it can have a little advantage in cost.

Therefore, it is necessary to find a way to increase the accumulation rate of source points.

In other words, if you want to find a way to learn with the highest efficiency, you have to learn the content with the highest output value at the source.

And to do this, the first step is to screen the directions.

Underlying or applied disciplines? Single-discipline or multi-discipline?

Theoretical or applied?

It's all a problem.

But fortunately, he is confident that he will never be limited by the so-called "university major", as long as it is what he wants to learn, the official should be as satisfied as possible.

Thinking of this, Chen Nian immediately took out his mobile phone and called Chen Guo.

The phone rang several times before it was connected, and Chen Guo's voice over there looked a little tired.

"Hey, Xiao Chen, I just wanted to call you."

"The results of the model validation are out, the data is good, very good!"

"In the next step, we will enter the practical verification link, we will apply for funds to build a physical wind tunnel for the aircraft, and then we need you to supervise and guide, and the school's affairs will be put aside for the time being......."

Hearing his words, Chen Nian nodded slightly.

The system really doesn't go wrong.

As long as the theory is verified, the results of the subsequent blowing tunnel must be no problem.

With the simulation data, he was able to give a stronger reason to draw the internal structure.

After all, there is nothing to do, and the structural diagram is drawn hard, and when others ask, he can't directly showdown and say that he has hanging........

Extrapolating the structure based on the simulated data is at least somewhat reasonable.

"Understood, Professor Chen, I can participate remotely when the time comes. But I need your help right now, do you remember the last time I told you I wanted a few teachers? ”

"Remember, I'm already arranged. What, can't wait? ”

"It's not."

Chen Nian shook his head and continued:

"I would like to ask you to help me do a survey and screen out the most efficient direction in the fields of materials science, mechanics, mathematics, and thermal."

"What does it mean to be the most efficient?"

Chen Guo on the other end was a little puzzled, according to his understanding, there is no distinction between disciplines, as for the efficiency of learning, isn't it decided by the person who learns?

"I mean, I need to find a subject that I learn the most per unit of time with a fixed amount of time and effort."

"You mean information density?"

"Yes, it's the highest information density!"

"Then don't think about it, it must be materials science....... Do you want to change majors? ”

Hearing Chen Guo's answer, Chen Nian had a feeling of "that's really the case".

Materials science....... This thing deserves to be the most important discipline in the history of human industrial application, and it deserves its name.

"No, I don't want to change majors, but I want to take another course in materials science, and the class hours should be improved!"

"If you can keep up, it's not too much of a problem....... I'll arrange it for you. ”

"Thank you very much. Another thing I would like to borrow from the school's materials lab. ”

"What?"

Chen Guo on the other end of the phone was shocked.

"You want to use the materials lab? What are you doing? ”

"I want to trial make Ti-6Al-4V titanium-aluminum alloy."

“....... Do it yourself? How? ”

"Powder casting and HIP processes are used, β annealing. I don't know if our lab has this condition. ”

"As far as I know, there are, but it's not enough for you to know the process principle, and many of the processing details are not something that can be imagined."

Having said that, Chen Nian's ability to accurately describe the manufacturing process of β-shaped titanium aluminum alloy has already surprised Chen Guo.

You must know that the manufacturing of such alloys is extremely difficult, even after more than 20 years, only the United States, Japan, and Russia have achieved large-scale mass production.

In this regard, China has always stayed in the laboratory preparation stage.

Even the J-20 only uses TC4-DT titanium alloy with relatively low strength and poor ductility.

Of course, the use of secondary materials also objectively reduces the weight of the body, but that's another story......

And now, as a student without any background in materials science, it is not easy for Chen Nian to know the chemical formula of titanium aluminum alloy, and he can still say the term hot isostatic pressing process.

How many surprises did he not show in front of him?

"I know, that's why it's called an experiment....... If it succeeds, then we can take a big step forward in terms of airframe materials. ”

"Okay, I'll help you get in touch, you don't use the school's laboratory, use the Western Research Institute, and deal with it according to the confidentiality process."

"But be careful, don't break their equipment---- you know, they're strapped for money."

"Understood, don't worry."

Hanging up the phone, Chen Nian breathed a long sigh of relief.

Two problems, solved at once.

At about four o'clock in the afternoon, he received a notice from Chen Guo that Guo Qi, an expert in powder metallurgy from the Western Research Institute, agreed to his request and was willing to lend him the equipment.

But the problem is that the entire Western Research Institute has no experience in powder die-casting titanium alloy before, so Chen Nian can only come by himself.

However, this is not a big deal for him, and the system has given him a full set of knowledge---- including the operation of the equipment.

One hour later, Chen Nian rushed to the materials laboratory of the Western Research Institute, where Guo Qi was already waiting for him.

"Chen Nian, right? I heard that you are Professor Chen's protégé. ”

Chen Nian smiled modestly and replied:

"I didn't dare to be, I didn't make any achievements."

"Regardless of whether there are achievements or not, if you can be recognized by Professor Chen, it is definitely not an ordinary person. I heard you want to synthesize β titanium-aluminum alloys? What is it used for? It can't be medical, right? ”

Although this type of alloy is widely used in the aviation field, it is also often used in the medical field, so it is not surprising that Guo Qi asked.

"No, it's the aviation field---- it's actually useless for the time being, it's just to test one of my own ideas."

"Okay, then you can toss it yourself."

"But let me tell you in advance, we only have one powder die casting machine here, which is very expensive. I will arrange for someone to take you to do it together, and you must not mess around without his instructions. ”

"If this thing breaks, we won't even be able to find replacement parts."

"I understand."

Chen Nian nodded hurriedly.

"It's good to understand."

After that, Guo Qi took Chen Nian into the laboratory, and in the laboratory, several experimenters who had already understood the situation in advance were getting together and whispering.

"Who is this man? Swaggering into the lab? ”

"The Aviation Institute of Xi'an University of Technology is said to be engaged in aircraft design, and I don't know how to let him get through the relationship, and even our laboratory can be borrowed."

"Oh...... Doctoral? ”

"Freshman."

"Freshman?! Are you kidding?! I don't dare let him use our equipment! ”

"It's useless whether you dare or not, Lao Guo has already agreed. Let's look at it for a while, and just deal with him. ”

"Does he really know what powder metallurgy is? You can't just read a concept in a book and run around and fool around, right? ”

"There is a high probability that today's students are all tigers and dare to do anything."

"Can you convince him to leave......."

"Don't be, the attitude is better, it's all about the world."

"Hey, no matter how sophisticated he is, he can't joke about this thing, he not only has to use a casting machine, but also HIP....... Forget it, I won't talk about it. ”

At this moment, everyone felt that Chen Nian was just a stunned young man who came to the laboratory to brush up his qualifications.

They look down on Chen Nian, it's obvious.

After all, in their eyes, seniority may not be important, and knowledge must be the first criterion for judging whether a person is good or not.

And how much knowledge can a freshman have?

What's more, it's still interdish.......

But what they didn't know was that at the first second of seeing the huge die-casting machine and the HIP hot isostatic pressing equipment next to it, a series of follow-up actions had already appeared in Chen Nian's mind.

This wave is stable.
