From all-round academic master to chief scientist - Chapter 154 The 19-year-old person in charge of key national projects

“The radii of atoms such as zirconium, niobium, and molybdenum are larger than the atomic radius of aluminum, so this will cause distortion of the crystal lattice and increase the volume of the unit cell.”

“In addition, the relative atomic mass of aluminum is only between one-third and one-quarter of those atoms.”

“If you compare the axle ratio…”

“The closer the axial ratio is to 1, the greater the degree of isotropy of the crystal, the weaker the covalent bonds between atoms, and the stronger the metallic bonds, which will affect the ductility of the final material.”

Lin Xiao recalled various theories and wrote some data on the manuscript paper.

Because he had the data converted from truth points in his mind, Lin Xiao seemed to have guidance. If his calculation conclusion could match this result, it would mean that the theory was correct.

And now, he is establishing such a theory.

However, this is still somewhat difficult.

Because the answers provided by the truth point are standard answers without a process. It’s like when you are doing a math problem and you encounter a question you don’t know, you want to copy the standard answer at the end, but you find that the standard answer has only one answer and the process is omitted.

So how to derive the final answer is the most critical.

For ordinary people, faced with such an answer, it may be completely impossible to connect the existing data with it.

But for Lin Xiao, when looking at these numbers, an occasional flash of inspiration may help him find his direction.

“If we start from the quantum chemical method… try the molecular orbital method first.”

Then, Lin Xiao started to try.

Although metals are composed of atoms, the formation of chemical bonds can still be solved using the molecular orbital method.

Here we need to use the solution of Schrödinger equation to describe the wave function of the electronic motion state.

In this way, Lin Xiao used more and more scratch paper, but it also made him addicted to it.

Entering the field of mathematics is like coming home. These mathematical symbols are all so cute and comfortable to write. I really like studying mathematics.

Ahem.

All in all, Lin Xiao now needs to find an unknown number that can reflect the gap between the calculated results and the actual results.

Time passed quickly.

These days, Lin Xiao did not come to the Aeronautical Materials Institute again, but stayed in his room, constantly constructing the theories he needed.

However, due to Cao Zhong’s request, he still compiled the report in advance and handed it to Cao Zhong.

Even without supercomputing, Lin Xiao’s calculation results on those software are generally enough to apply for funds.

So Cao Zhong planned to try it first. If he could get the funds as early as possible, it would be best to get the funds as early as possible.

A few days later, a meeting was held among the top management of the Aviation Development Group.

The people attending this meeting were all senior executives of the Hangfa Group. In addition to Cao Zhong, there were also the general manager of the Hangfa Group and several other academicians.

“Old Cao, what are you going to do at this meeting?”

Cao Zhong did not answer, but said first: “We will talk about it later. Let’s all sign a confidentiality agreement first.”

Seeing Cao Zhong being so solemn, everyone present was stunned.

“Confidentiality agreement? What is so important?”

“Old Cao, have you made any major breakthroughs?”

Upon hearing the “major breakthrough”, these people’s eyes also lit up. As a group that specializes in the research and development of aero-engines, they have signed many confidentiality agreements, large and small. Of course, they can guess what the situation is that requires them to sign confidentiality agreements. protocol.

Cao Zhong had no expression on his face and looked tight-lipped as he said, “Don’t ask first. It’s a rule. Sign first.”

Soon, confidentiality agreements were handed out to everyone present, and everyone present signed the confidentiality agreement without any nonsense.

“You can finally talk about it now, right?”

Until the confidentiality agreement was collected, an academician asked again.

Cao Zhong still didn’t say anything, but put the confidentiality agreement away first. After reading it for a while, he then looked at the doors and windows in case the walls had ears. Then he handed out the printed reports one by one from the file bag. .

The people present had been waiting impatiently for a long time. When they got the report, their faces suddenly showed shock.

“Titanium-aluminum alloy? Can it be used in turbine fan blades? This mechanical strength… is this true or false?”

An academician was shocked and said, “As long as this material is real, the thrust of our engine can be increased by several points! Moreover, the density of titanium-aluminum alloy is low. By then, it will not be a problem for the thrust-to-weight ratio to exceed that of the American F22 engine!” “

This academician’s surname is Liu, and his name is Liu Xiangkong. He has a very high status in the domestic aviation field and can be said to have the highest qualifications in their aviation development group. He was so surprised, of course, because the nature of this material really surprised him. It feels incredible.

Everyone else also looked surprised.

But at this time, someone discovered the problem and said, “No! This material was calculated and simulated? Then Lao Cao, aren’t you kidding us? Can computational simulations be taken seriously?”

Hearing this sentence, others reacted and looked back, and it turned out to be the result of calculation and simulation.

They all immediately looked at Cao Zhong, wanting to see what he would say later.

Cao Zhong smiled and said, “If this is true, can I just ask a few of you to come over for a meeting?”

If the material entity had been produced and verified long ago, he would not be holding a meeting here, but would directly write an internal parameter.

Hearing what Cao Zhong said, everyone else looked at each other: “Then what do you mean?”

“I think we should allocate funds specifically for the production process design of this material, and then set up a research team to develop it. At least, it has to be five million, right?”

Cao Zhong looked at Li Yong, general manager of the group, “Mr. Li, you still have to approve this matter.”

Li Yong shook his head and said: “Five million is not enough. Your results are not convincing.”

Although as general manager, Li Yong is mainly responsible for administrative affairs, he certainly understands these professional matters. The main power to approve the group’s funds is in his hands, and of course he cannot just approve it casually.

Cao Zhong smiled slightly, no nonsense, and then took out a series of data reports, which were the results of simulations produced by various software that Lin Xiao had used before, and then gave them to these people to read.

These results have more data and are more comprehensive. From molecular dynamics to lattice dynamics, from phonon spectrum to phonon partial wave state density diagram and other analyses, each conclusion shows this The material has extremely excellent properties.

The academicians and experts who originally thought that Cao Zhong came here to make them happy were speechless at this time.

At the same time, like Cao Zhong when they saw the calculation results presented by Lin Xiao, they all began to think, what if it can really succeed?

“This…” Li Yong opened his mouth and said after a while: “Is five million… enough?”

Hearing what Li Yong said, Cao Zhong showed a smile on his face: “If it’s not enough by then, just do it again.”

If there is a chance of success, why don’t you approve it?

And the academician Liu Xiangkong stood up directly: “Approval, it must be approved! In the past, if the country spent hundreds of millions or billions, it might not be able to make a splash. Now, with only a few million, there is a chance of success, and it can still Not approved? If you don’t have money, go to the National Yuan and ask for it!”

Seeing that the most senior person had spoken, Li Yong was naturally unable to stop him. “Okay, Academician Cao, you go and submit the project application. We will use special channels and the money will arrive within a week.”

However, when they said this, they suddenly realized who made this calculation result? Who will the research team be composed of then?

Li Yong then asked this question: “Academician Cao, who wants to apply for this project? It can’t be you, right?”

Because he signed a confidentiality agreement, Cao Zhong smiled and said: “Lin Xiao, you know, right?”

“Lin Xiao?”

Everyone present was stunned. Is there such a great person in the domestic computing materials field?

However, at this time, someone thought: “Hey, I learned from Academician Chen Bao before that Lin Xiao, who proved Goldbach’s conjecture, seems to be in his research group, right? What you wouldn’t say, Lao Cao, is Him?”

“Yes, that’s him.”

Cao Zhong smiled and nodded.

Hearing Cao Zhong’s confirmation, these academicians and experts were shocked again.

“This…how is this possible? Isn’t he studying mathematics? How come he has such in-depth research on computational materials science?”

If you want to calculate this kind of results through computational materials science, you don’t just need to input data and adjust various parameters. This not only requires sufficient knowledge reserves, but the application of this knowledge is also very important.

It’s like designing a program. A good programmer may be able to complete a program in five lines of code, but a bad programmer may not be able to complete it in more than a dozen lines, and will eventually have to find bugs.

Even if Lin Xiao is great in the field of mathematics, why is he so good in computational materials science now?

Seeing the surprised expressions of these people, Cao Zhong couldn’t help but remember that when he learned from Chen Bao that Lin Xiao was still engaged in computational materials science, wasn’t it the same?

With a slight emotion in his heart, he then said: “You should not use common sense to understand some people. Lin Xiao belongs to this kind of person.”

Hearing what Cao Zhong said, these people immediately nodded, feeling deeply convinced.

…

The funds could be approved, so Cao Zhong naturally conveyed the good news directly to Lin Xiao and Chen Bao.

“Five million?” A smile appeared on Chen Bao’s face: “It should be possible to experiment twice, not bad.”

“Haha, don’t worry, five million is not enough, let’s apply for more.”

A smile appeared on Cao Zhong’s face, and then he said to Lin Xiao: “By the way, Lin Xiao, let’s add your contact information. I will send you the project application form. You fill it out and give it to me. Then go through special channels. One The funds will be approved within the week.”

Lin Xiao was stunned: “Should I apply? But I can’t design experiments.”

“Of course you apply.” Cao Zhong shook his head: “This is the material you designed. You are naturally the leader of this research group, so the credit belongs to you. Otherwise, those of us who are engaged in computing materials in China will find someone to help design When conducting experiments, we have to give the primary credit to others. Do you think there are still people who are willing to engage in computational materials science?”

Chen Bao also smiled and said: “It’s yours, just take it. Just invite me to come to the research team to help. Moreover, in this way, you will become the youngest person in charge of key projects in our country. Nineteen Sui, don’t you want to try?”

After hearing what the two academicians said, Lin Xiao stopped giving in and said, “Then I’ll trouble Academician Cao.”

…

A week later.

A research team on the design of a new titanium alloy production process was secretly established. Now only 19 years old, Lin Xiao has become the person in charge of what can be called a national key project, and the members of the research team are all academicians. Lord.

If such a lineup were spread, it would probably surprise countless people.

An academician actually works for a 19-year-old young man?

However, due to the secrecy of this subject, not many people know about it. In addition to the members of the research team, there are currently no more than ten people who know about this research team.

For Lin Xiao and others, they don’t need others to know, all they need to do is to do their task well, that’s all.

In this way, time passed quickly.
