Spark

After confirming that the system can resolve smaller units, Chen Nian immediately realized a serious problem:

The source point acquisition speed is really too slow.

According to the current progress, it will cost 0.1 source point just for a mostly known titanium alloy material.

Although it doesn't look like much, it's the amount he can brush out in three days.

How long would it take to make an F-22?

Even if it only solves the most critical problems, the sum is not a small number.

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

Therefore, we must find a way to increase the accumulation speed of the source point.

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

To do this, the first step is to select the direction.

Do you study underlying subjects or applied subjects? A single subject or a combination of subjects?

Take the theoretical route or the applied route?

These are all problems.

But fortunately, he is confident that he will never be restricted by the so-called university major. As long as it is something he wants to learn, the official should be satisfied as much 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 seemed a little tired.

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

The results of the model verification came out, the data is very good, very good!

The next step, we will enter the practice verification link. We will apply for funds to manufacture the physical air blowing tunnel of the aircraft. At that time, we will need you to supervise and guide us. Let's put aside the school affairs for now.

Hearing his words, Chen Nian nodded slightly.

Sure enough, there will be no problems with the system.

As long as the theoretical verification is passed, the result of the blowing tunnel at the back must be no problem.

With the simulated data, he can have a stronger reason to give the internal structure drawings.

After all, he didn’t have anything, and he just drew a structural diagram. When others asked him, he couldn’t just show his cards and say that he was involved.

It is at least somewhat reasonable to push the structure based on the simulated data.

Understood Professor Chen, I can participate remotely at that time. But I need your help with something now. Do you remember the last time I told you that I wanted a few teachers?

Remember, I'm already making arrangements. Why, can't wait?

no.

Chen Nian shook his head and continued:

I would like to ask you to help me do a research to select the most efficient direction in the directions of materials science, mechanics, mathematics, and thermal science.

What is the most efficient?

Chen Guo at the other end was a little puzzled. According to his understanding, there is no distinction between subjects. As for the efficiency of learning, isn't that determined by the person studying?

What I mean is, I need to find a subject that can learn the most per unit of time with a fixed investment of time and energy.

You mean information density?

Yes, it has the highest information density!

Then don't think about it, it must be materials science. Do you want to change your major?

Hearing Chen Guo's answer, Chen Nian had a feeling of it really is.

Materials science is indeed the most important subject in the history of human industrial application, and its reputation is well-deserved.

No, I don't want to change my major, but I want to take another course of materials science, and the class time needs to be improved!

If your energy can keep up, there is no big problem. Let me arrange it for you.

Thank you very much. There is another thing, I want to borrow the school's materials laboratory.

What?

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

You want to use the materials laboratory? What do you want to do?

I want to try to produce Ti-6Al-4V titanium aluminum alloy.

.You do it yourself? How?

Powder casting, hot isostatic pressing, and beta annealing are required. I don't know if our laboratory has this condition.

As far as I know, there are, but it is not enough for you to know the principle of the process. Many of the processing details cannot be imagined.

Having said that, Chen Guo was greatly surprised by Chen Nian's ability to accurately describe the manufacturing process of β-type titanium-aluminum alloy.

You must know that the manufacture of this type of alloy is extremely difficult. Even after more than two decades, only the United States, Japan, and Russia have achieved mass production.

In this regard, China has always remained at the stage of laboratory preparation.

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

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

But now, as a student without any background in materials science, Chen Nian is not easy to just know the chemical formula of titanium-aluminum alloy. He can even say the term hot isostatic pressing process.

How many surprises are there that he didn't 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 airframe materials.

Okay, I'll help you get in touch. You don't need to use the school's laboratory, but use the one from the West Research Institute. It will be handled according to the confidentiality process.

But be careful not to screw up their equipment—you know, they're on a tight budget.

Understood, don't worry.

After hanging up the phone, Chen Nian breathed a sigh of relief.

Two problems, one solution.

After four o'clock in the afternoon, he received a notification from Chen Guo that Guo Qi, an expert in the field of powder metallurgy of the West Research Institute, agreed to his request and was willing to lend him the equipment for use.

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

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

An hour later, Chen Nian rushed to the materials laboratory of the West Research Institute, and Guo Qi was already waiting for him there.

Chen Nian, right? I heard that you are Professor Chen's favorite student.

Chen Nian smiled modestly and replied:

Didn't dare to be, didn't make any achievements.

Regardless of your grades, if you can get Professor Chen's approval, then you are definitely not an ordinary person. I heard that you want to synthesize β-type titanium-aluminum alloy? What is it for? It can't be medical treatment, 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 this question.

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

Okay, then you can toss it yourself.

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

If this thing breaks, it's hard for us to find replacement parts.

I see.

Chen Nian nodded quickly.

As long as you know.

After all, Guo Qi led Chen Nian into the laboratory, and in the laboratory, several experimenters who had known the situation in advance were whispering together.

Who is this person? Walking into the laboratory swaggeringly?

The Aeronautical Academy of Xigong University is said to be engaged in aircraft design. I don't know how to let him get through the relationship. He can even borrow our laboratory.

Oh doctoral student?

Freshman.

Freshman?! Are you kidding me?! I dare not let him use our equipment!

It doesn't matter whether you dare or not, Lao Guo has already agreed. Just watch it later, and just deal with him.

Does he really know what powder metallurgy is? He didn't just read a concept in a book and then ran over to mess around?

The high probability is that the current students are all bullies and dare to do anything.

Can you persuade him to leave?

Farewell, please have a better attitude, it's all about the world.

Hey, no matter how sophisticated the world is, you can't make fun of this thing. He not only needs to use the casting machine, but also the HIP. I won't talk about it.

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

It was obvious that they looked down on Chen Nian.

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

And a freshman student, how much knowledge can he have?

Moreover, it is interdisciplinary

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

This wave is stable.
