From Almighty Scholar to Chief Scientist

Page 86

So he immediately asked in his heart: "System, if molybdenum atoms are used to replace aluminum atoms, can the creep resistance be improved by 50.00%? How many points of truth do you need for this question?"

System: "This question requires 13 truth points."

Lin Xiao then asked: "What if zirconium atoms are used instead of titanium atoms?"

"This question requires 13 truth points."

"It is the same?"

Hearing this answer, Lin Xiao frowned.

In a single unit cell, the difference caused by replacing aluminum atoms with molybdenum atoms and replacing titanium atoms with zirconium atoms should be very large. How can the truth be the same?

He used his 4.35% brain to think carefully, and suddenly guessed a possibility, so he asked again: "How can we increase its creep resistance by 50.00%?"

"This question requires 13 truth points."

The sound of the system sounded as usual.

Now, Lin Xiao couldn't help guessing.

The system does not care about the distance from the direction to the target, but only the absolute distance between the target and the current stage.

The absolute distance is the price it ends up giving.

Just like if he goes north from the Institute of Aeronautical Materials, he may arrive at Beijing University in a few kilometers, but if he goes out and goes south, he has to go around the world, but the distance between his starting point and destination The distance is still so much.

Therefore, the idea of judging the success of the research direction based on the quotation given by the system is basically useless.

Unless you spend some time doing research in this research direction, and then determine whether your direction is correct through whether the system quotation has decreased.

If this is the case, you can still go whoring for nothing, at least you can confirm whether your direction is correct in time, and avoid entering a dead end, but it does not rule out that after research, you already know whether the direction is correct, and there is no need to ask when the time comes.

Shaking his head, Lin Xiao gave up on the idea of a prostitution system.

However, it takes 50.00 truth points to increase the creep resistance of their TiAl alloy by 13%, so how much does it take to increase it by [-]%?

He immediately asked this question in his mind.

"This question requires 29 truth points."

29 truth points!

Lin Xiao was shocked, it was so expensive!

But he thought for a while, and asked again: "If you can improve its strength, oxidation resistance, volume stability, and high-temperature structural stability to a certain extent, how much will it cost?"

"This question requires 44.2 truth points."

Only increased by 15.2 truth points?

Lin Xiao thought about it carefully, probably because there will be repetitions between meeting these requirements, for example, if the creep performance is strong, the high-temperature structural stability will also become stronger.

However, this 44.2 truth point... doesn't seem unacceptable to him?

He suddenly asked Chen Bao next to him: "Academician Chen, what if we can improve the creep resistance of this thing by [-]%?"

"One hundred percent? Boy, I think it's good to increase it by 30.00%. It will definitely be no problem to be a candidate material for our turbofan-15 engine wall panels in the future. You have increased it by one hundred percent." , is it going to be built directly on the fan blade?"

Chapter 149 A Coincidence Encounter by the Unnamed Lake

Hearing Lin Xiao's question, Chen Bao couldn't help laughing.

The material he is expected to study in this project is the application on the engine panel.

Especially fighter jet engines.

Fighter engines are generally small bypass ratio engines, unlike civil aviation engines with large bypass ratios. The high temperature resistance requirements of high bypass ratio engines are not as high as those of small bypass ratio engines.

In fighter jets, the service temperature of the engine wall plate is generally around 600°C, sometimes even higher, and the main stress it bears comes from mechanical loads and high-frequency vibrations.

As for the service temperature of the fan blade, it is as high as over [-] degrees Celsius, which is almost the highest temperature in the entire engine, and the rotation speed of the fan blade is quite fast, which makes the stress more complicated, which is enough to see that the fan blade has to bear How bad the environment is.

For the engine, there is an important indicator, that is the temperature before the vortex.

Generally speaking, for every 100K increase in the temperature before the vortex, the engine thrust can be increased by at least 10%, or even increased by 20%.

Therefore, the higher the high temperature resistance of the fan blade, the higher the temperature before the vortex.

How to keep the fan blades strong at such a high temperature is a challenge for material researchers all over the world.

Therefore, the blade of an aero-engine is the most difficult material to prepare and develop. Its requirements for high temperature, high pressure and high strength make it known as the jewel in the crown of industry.

And Lin Xiao said that he wants to increase the creep resistance of their material by 100%, which is completely whimsical. If the creep resistance is increased by 100%, then the high-temperature structural strength of the material must be improved accordingly, right? There are other performance can also be improved?

Isn't this going straight to the material of the fan blade?

Then they would have to conduct more and more complicated experiments, and it would take an unknown amount of time for this, and it might not be successful in the end.

For Chen Bao, he has also developed towards this before, but in the end he chose to give up. If he wants to produce this kind of material, he does not have enough determination and perseverance, and he must have a steady stream of resources. Willing to give resource support all the time, who can guarantee that no one else will say something bad?

Now it’s not 60 years ago when the whole country was concentrating on making mushroom eggs.

Hearing Chen Bao's words, Lin Xiao smiled: "I'll just ask casually."

Chen Bao shook his head: "Titanium-aluminum alloys may have this potential, but we are definitely in the wrong direction. We need to start with the atomic arrangement structure, and consider the development of single-crystal directional solidification, but then the funding I want to apply for may be limited. There will be two or three more zeros in the back."

Their research funding for this topic is several million. If two or three zeros are added to this, it will go straight to nine or ten digits.

However, the development cost of any fighter engine is not a matter of hundreds of millions, but tens of billions or hundreds of billions. As the core component of the fan blade material, the research and development cost is hundreds of millions or billions. Accident.

Hearing Chen Bao's words, some graduate students around asked, "Boss, among the projects you have participated in before, what did you invest the most in?"

Chen Bao said with a smile: "C919, J-35, and J-[-] have also participated, and I have participated in the research on materials. These are big projects worth tens of billions."

"Wow!"

Immediately, the graduate students present showed expressions of admiration.

This is an academician of materials science!

"Okay, don't talk about it, that's it, the hero will not mention the bravery in the past, let's continue our research."

Chen Bao waved his hands, as if he was not a good man.

Hearing what Chen Bao said, the others nodded and started to continue with the work.

Lin Xiao looked at the things in front of him thoughtfully.

"System, if I ask a question worth more than 30 truth points, can the answer worth 30 truth points be included?"

System: "Yes."

Lin Xiao nodded slightly, that's all right.

Since it can be converted into when answering questions with more than 30 truth points, then he can now add 14.2 truth points to obtain the model of this new material.

However, this matter is also not in a hurry. He can study it first, and wait until he has achieved certain results, that is, after the absolute distance from his ultimate goal is shortened, and then use truth points to buy it. Maybe he can save some of it by then. point of truth.

So he smiled slightly on his face and said, "Academician Chen, let's try it now, titanium 7 aluminum 8 zirconium 1?"

"Well, try it on here now."

Chen Bao responded.

Subsequently, the calculation simulation of the second stage began.

……

Time passed quickly, and it was another ten days.

Entering April, the temperature is gradually warming up, and the weather around [-] degrees is just the most suitable temperature.

Because they identified a new material, they entered the link of new material production process design again. Lin Xiao didn't have anything to do, so he came to the campus of Shangjing University to enjoy the breath of spring.

"Well, it's been a long time since I've been in such a comfortable sun."

Walking by the Weiming Lake, bathed in the sun, Lin Xiao squinted his eyes comfortably, but it was a pity that he didn't bring Mimi here, otherwise it would be very comfortable to sit on the lawn and pet a puppet cat.

Suddenly, he felt someone slapped him on the back, and when he turned his head, he couldn't help showing surprise on his face: "Oh, Sun Yu, it's been a long time."

Sun Yu was speechless: "I should be the one who said this to you, right? I was able to see you in the school. It seems that you haven't forgotten that you are from the University of Beijing?"

Lin Xiao shrugged: "The college allows me not to attend classes, so of course I will not attend classes."

Sun Yu couldn't help complaining: "You are outrageous. You don't take a class. It's fine to get full marks in mathematics and other subjects. You can also get full marks in Sixiu. I don't know how you learn. Good guy, just get a 4.0 grade. Point, we are all number one."

Lin Xiao laughed and said, "If you count my thesis proving Goldbach's conjecture, it should be more than 4.0."

Sun Yu: "...you are awesome."

It's still the familiar formula, the familiar taste, and Lin Shen is showing off again.

At this time, a pretty girl came to Sun Yu's side.

When Sun Yu saw this girl coming, he put his arms around her shoulders and said to Lin Xiao, "This is my girlfriend, Yu Man, from the Wuyuan."

"Manman, look, let me tell you, Lin Shen and I are good brothers who have won glory for our country together."

"Hello, Lin Shen."

Lin Man also called Lin Xiao.

Lin Xiao: "..."

"Where did you find your girlfriend?"

"It's not easy to find a girlfriend...ah no, it's hard to find a girlfriend, the main thing is to put your heart into it, you have to be good at discovering, and then use your knowledge to conquer her, isn't it? Manman? "Sun Yu looked at Yu Man.

Yu Man put down the hand that was about to pinch Sun Yu, then nodded with a smile, and then said to Lin Xiao: "It must be easy for Lin Shen to find a girlfriend. The girls in our school often talk about you. If you want to find a girlfriend Girlfriend, tell me, I'll greet them directly."

"No need, no need." Lin Xiao waved his hand.

Sun Yu laughed and said: "Shen Lin is not like us mortals, Manman, don't even think about it, let him go alone."

Lin Xiao: "..."

Believe it or not, I will find you a girlfriend right away?

With how handsome we are, why can't we find a girlfriend?

"By the way, Lin Shen, do you want to form another team? To participate in the Qiu Chengtong Math Competition, we will have a stable subject."

Then Sun Woo asked.

Lin Xiao waved his hand: "I won't go, I'm taking part in a project recently."

"Problem? Mathematics and physics? I remember you told Mr. Yang that you were participating in this subject?" Sun Yu was taken aback and asked.

"No, that subject is over, now it's about materials science."

"... Has physics been unable to stop you from growing old?"

"Interested."

"...Sure enough, I shouldn't have asked."

Sun Yu gave up the conversation with Lin Xiao, and then said: "My girlfriend and I continued to go shopping, you continue to shine for our mathematics community."

Lin Xiao said with a smile: "Go ahead, I won't bother you. By the way, Yu Man, you have to keep an eye on him. This guy used to share videos of beautiful women with us."

After speaking, he turned his head and left.

"Damn, you slandered me! Manman, don't listen to him, he slandered me!"

"Just let me see your video browsing history."

"Ah this..."

……

Lin Xiao, who had already walked away, snorted and showed me his girlfriend, right?

let you show.

It's better to go home and pet the cat.

Thinking of this, Lin Xiao planned to go back.

However, everyone probably thought that today was a time, and not long after, Lin Xiao met another acquaintance.

Kong Huaan.

It was the roommate that Lin Xiao met when he participated in the National Mathematics Training Team.
