Chapter 742 A new subject

After some cordial and friendly exchanges, Tang Lintian finally agreed to adjust the number of class hours and assessment methods for basic courses as soon as possible, and Chang Haonan also promised to allow two senior students to participate in public practical projects through his research group every year.

When students who are included in this training method graduate, in addition to the normal degree certificate and graduation certificate, they will also receive a certificate of participation in the "Excellent Engineer Training Program".

It can be regarded as a satisfactory result for both parties.

"Now that the matter is over, I won't bother you any more."

After receiving Chang Haonan's assurance, Tang Lintian put down his empty glass, stood up and prepared to leave.

As the host, the former naturally could not let the other party go alone, so he quickly got up to see him off.

When taking the elevator downstairs, perhaps to avoid being left in the cold, Tang Lintian asked casually:

"Professor Chang, I wonder what research direction you plan to choose first after the Torch Laboratory is established?"

"Well...two levels."

Chang Haonan thought seriously for a moment until the elevator reached the first floor and the two of them walked out before answering:

“After all, the laboratory as a whole has just been established, and I’m afraid it won’t be able to do any particularly difficult topics, so I plan to find a few less difficult projects in the aviation system to practice my skills on, and also to enhance the understanding among the members of the research team. "

"As for myself, I plan to focus on materials science next. Of course, as I said during my defense in the morning, I will study the application of inertial manifolds in dissipative partial differential equations, which naturally also includes the application of NS equations. But later This research is at the level of mathematical theory and relies more on inspiration, so it is difficult to have a definite timetable.”

"Material science? Our school doesn't have much research foundation in this area..."

Tang Lintian was not from Neo-Confucianism and did not know much about cutting-edge mathematical theories, so he decisively gave up studying the last half of the sentence.

"Well, of course I know that."

Chang Haonan nodded:

“So, what I’m going to go into is a new direction, combining numerical methods with materials science research.”

Looking at Tang Lintian's slightly confused eyes, he had no choice but to give a further explanation:

"Simply put, it is to conduct directional analysis and calculation of the characteristics, structure, components, and processing technology of materials through physical modeling and numerical calculation methods."

"Compared with the traditional research method of materials science, which is close to alchemy, once my idea is realized, it will have obvious advantages in terms of predictability and regularity."

“Doesn’t that mean that in the future, the field of materials science may be like our aircraft design, where users give a series of performance parameters, then carry out targeted designs, and finally provide customized processes and processing solutions?”

In terms of engineering, Tang Lintian's ability to draw inferences from one instance is quite strong.

Moreover, he originally came from computational fluid dynamics, so it is naturally easy to make analogies to his own research field.

"That's right, but the simulated objects are different."

Chang Haonan smiled:

"Well, materials science mainly focuses on particle relationships at the microscopic level or multi-field composite relationships at the macroscopic level. The requirements for computing power and algorithm design are not exactly the same as computational fluid dynamics."

Tang Lintian also knew that he had basically reached the top in scientific research, otherwise he would not have turned to full-time administration, so he was self-aware and did not discuss the technical details in depth, but changed the subject:

"This...should be considered a new subject? At least I've never heard of it before."

"In fact, this research direction has existed for a long time. Not to mention others, I myself completed a special steel-related development project the year before last, using the method just mentioned."

What Chang Haonan was talking about was the time when he designed the bearing steel formula and process for the three major bearing groups.

To a certain extent, it can be regarded as an indirect result of the concentrated decline of a large number of Japanese brands represented by NSK and NTN Group in the European market.

A large wave of whale (shark) losses has also revitalized many companies from China, South Korea, Eastern Europe and even Southeast Asia.

Looking at Tang Lintian who was already a little stunned next to him, Chang Haonan paused for a moment, letting the other party relax a little before continuing:

"Including the recent production acceptance process for heavy-duty die forging presses, I also tried to use numerical methods to guide the research and development of titanium-aluminum alloy forging processes. Judging from the results, the overall efficiency has been improved by about 40%."

"However, so far, research in this area is indeed relatively scattered and has not formed a complete discipline. If I were to say it, it might be called 'computational materials science'."

Different from the situation more than 90 years later, when everyone went to materials science journals to fill the gap, in the late s, materials science could not be regarded as a prominent science, and it was still a relatively weak part in China.

But precisely because of this, the input-output ratio will look even better——

In order to make up for the shortcomings in the field of materials, technicians are often forced to perform at a higher level in other parts such as design optimization.

In this case, when material science in turn fills in the shortcomings, it will often have the effect of affecting the whole body.

As has been achieved previously in the field of bearing gear steels.

"Then, I wish Professor Chang success in his new research direction!"

For Tang Lintian, after successfully getting his school into the top C10 league in China, he indeed feels like he has lost his life goal.

But now, it seemed that another golden opportunity appeared in front of him.

Create a new discipline.

It is true that this kind of thing cannot be done by one person alone.

But there must be one person who can be the core.

"If you have any problems, the school will try its best to help you solve them!"

Before getting on the bus, Tang Lintian shook hands with Chang Haonan again.

In fact, considering that the latter is already considered a "half-step academician" and is about to take up the post of chief planner of the Aviation Power Group, if we really count, the resources at his disposal are actually more than those of the president of Beijing Airlines. Tang Lintian only had more.

But no matter what, the attitude must be put here first.

Moreover, no one would support too much, right?

……

After the doctoral defense was settled, Chang Haonan did not immediately engage in new work, but planned to rest at home in Beijing for a while.

After all, the test flight process of Turbofan 10 is going well now. As for setting up a laboratory...

The candidates for several lecturers have been basically determined, but the next class of students will not be able to start contacting them until August or September at the earliest.

It's okay if you are exempted from the postgraduate entrance examination. If you are a student preparing for the postgraduate entrance examination, you won't be able to ask others to come over to work at least before the initial examination.

I can't rush this moment.

Moreover, in the nearly five months since the Spring Festival holiday in February, he has been traveling almost non-stop between Jiangcheng and Beijing, occasionally taking time to listen to the returns from the Taihang project.

Definitely needs to loosen up a bit.

However, the idea is beautiful.

At Chang Haonan's current position, his time no longer belongs entirely to him.

Before he could enjoy a few days of relaxation, he received a call from Ding Gaoheng.

In the more than half a month before and after his defense, a lot of things happened.

The most important one is——

The fragment of the B2 bomber was carried back by Lao Wu among a pile of sample materials from the Azov Steel Plant.
