Obviously, Lin Yunwen's reaction was a little big, pointing at Wang Xudong, Chen Sanlian, and Ding Huixian, and said in an excited and hurried tone: "You... You are faking it, it is impossible, it is absolutely impossible to have such stainless steel materials, not to mention that we are domestic, even foreign developed countries cannot have it.

Lin Yunwen is an excellent aero engine expert, naturally not a layman about materials, on the contrary, he knows materials very well, especially metal materials, has a good level, and knows the current level and status of metal materials at home and abroad.

It is precisely because he also has good attainments in the field of materials that Lin Yunwen can make reasonable and scientific use of various materials, especially metal materials, in the design of aero engines.

This introduction to super stainless steel is more detailed, not only in terms of corrosion resistance, but also about its mechanical properties and processing properties.

Seeing that the mechanical properties of this stainless steel material are so excellent, especially in terms of fatigue strength, yield strength, pull-up strength, etc., it is almost inferior to high-strength steel. Suddenly, Lin Yunwen realized that there was absolutely no such stainless steel material.

Lin Yunwen believes that Sanlian Special Steel must be cheating, and it is also boasting more powerfully, originally came with great hopes, did not think about it, hope was disappointed, it is conceivable that Lin Yunwen's reaction is huge.

Xu Jiaxiang hurriedly asked with concern: "Lao Lin, what's wrong with you?"

Lin Yunwen said angrily: "Lao Xu, take a look, take a serious look, you are an expert in metal materials, do you think it is possible to have this kind of stainless steel material in our country?"

Xu Jiaxiang frowned, carefully and carefully, turning page by page, and the more he looked at it, the more dignified his face became, and when he got to the back, his eyebrows were twisted into a Sichuan shape.

Wang Xudong guessed why Lin Yunwen's reaction was so big, Wang Xudong smiled, Chen Sanlian also laughed, Ding Huixian shook his head even more, and thought in his heart, if this stainless steel material was not smelted by himself, he really couldn't believe it.

After carefully reading this introduction carefully, Xu Jiaxiang said in a deep voice: "Lao Ding, what's going on?"

Ding Huixian said slowly: "Lao Xu, I know you may not believe it, but the fact is true, we have indeed successfully smelted this stainless steel material, and the data on this introduction is not false at all, it is true!"

Lin Yunwen was so angry that his chest rose and fell in anger, and he said loudly: "At this time, you still have to lie to me, you are definitely a fake, and it is impossible to have such a stainless steel material." ”

Xu Jiaxiang and Ding Huixian were many friends, knowing that Ding Huixian should not tell lies, Xu Jiaxiang asked seriously again: "Lao Ding, is there indeed this kind of stainless steel material?"

Ding Huixian nodded affirmatively.

Wang Xudong said: "Two experts, our Sanlian Special Steel has indeed smelted this very remarkable stainless steel material, we have samples in the laboratory, if you don't believe it, let's go over and take a look, and you can even do a test in person to detect whether this stainless steel material is fake." ”

As soon as Wang Xudong said this, Xu Jiaxiang nodded, agreeing with this, it is a mule or a horse, you will know it when you pull it out for a walk, not to mention, Xu Jiaxiang himself is an expert in metal materials, and it will be clearer when he looks at the sample and then does the test.

Lin Yunwen didn't believe it at first, but when he saw that Wang Xudong was talking about this, he believed it a little more, and said hesitantly: "Mr. Wang, is what you said true?"

Wang Xudong said with a smile: "Expert Lin, if you don't believe it, you can leave now, but don't regret it, there is no regret medicine in the world." ”

Feeling Wang Xudong's strong self-confidence, Lin Yunwen believed it a little, and wondered in his heart whether he had reacted a little too much just now, too impulsive.

Lin Yunwen smiled wryly and said apologetically: "Mr. Wang, I'm really sorry just now, I reacted a little bigger, you guys laughed." ”

Lin Yunwen was able to bend and stretch, realized his impulse just now, and apologized in front of everyone, Wang Xudong nodded, waved his hand and said, "Let's go, then let's go to the laboratory." ”

Under the leadership of Ding Huixian, everyone soon came to the laboratory, Ding Huixian picked up a super stainless steel bar and introduced: "Lao Xu, Lin expert, this is the super stainless steel we smelted, this is a bar, and there are some plates here." ”

That's super stainless steel!

Suddenly, Lin Yunwen and Xu Jiaxiang picked up a rod, took it seriously, and looked carefully, Xu Jiaxiang deserved to be an expert in metal materials, so he immediately nodded, because Xu Jiaxiang saw that this stainless steel material was indeed different from ordinary stainless steel materials, and it seemed to be more pure.

Lin Yunwen also seemed to feel that it was different from the stainless steel material he usually dealt with, and asked, "Old Xu, have you found anything?"

Xu Jiaxiang nodded and said: "It feels really different, if you want to be sure, you must first do a metallographic analysis and take a look at the microstructure of this stainless steel material." ”

Metallographic analysis can be done in the laboratory, Ding Huixian said loudly: "Xiao Liu, do a metallographic analysis immediately, we have to see the results again." ”

"Okay, no problem. Xiao Liu replied loudly, and then began to take samples and began to do metallographic analysis.

Taking advantage of Xiao Liu's metallographic analysis, Ding Huixian began to introduce this super stainless steel material in more detail again, although there were still some doubts in his heart, but seeing Ding Huixian's serious introduction, it was not like bragging at all, Lin Yunwen and Xu Jiaxiang quietly glanced at each other again.

Xu Jiaxiang said: "Lao Ding, if your introduction is true, there is no exaggerated composition, then this stainless steel material is amazing, this will be the world's best, the highest technology stainless steel material, the use will also be very wide, in the history of the development of metal materials in the world, this will be a milestone." ”

Ding Huixian's introduction naturally did not exaggerate at all.

It didn't take long for Xiao Liu's metallographic analysis to be done, and he shouted loudly: "Expert Ding, it's all right, you can come and take a look at this microstructure." ”

Everyone walked over together, and after magnifying tens of thousands of times under the electron microscope, the microstructure of this stainless steel material was clear and clear.

It can be seen that the microstructure of this stainless steel material is very symmetrical, very clean, almost no impurities, no cracks and so on.

General metal materials, under the electron microscope, after magnifying tens of thousands of times, their microstructure is generally not very uniform, and there are some inclusions, some tiny cracks, etc., the existence of these things will affect the performance and strength of this metal material.

And the stainless steel material in front of me almost does not exist such a thing, the organization is very uniform, it looks very beautiful, clean, there are no impurities, no tiny cracks and so on.

"Oh my God, unbelievable!"

Dealing with metal materials all year round, Xu Jiaxiang naturally saw the unusualness at a glance, and immediately exclaimed, even excited, and said in a slightly trembling tone: "Lao Lin, it seems that you are wrong to blame others, they are not cheating, they are not bragging." ”

Just by looking at the metallographic analysis, Lin Yunwen knew that he was really wrong in his estimation just now, and Lin Yunwen was full of apologies in his heart, "Mr. Wang, Mr. Chen, I really had a little impulse just now." ”

Wang Xudong smiled generously and said unconcernedly: "It's okay, it's a trivial matter, don't take it to heart." ”

Wang Xudong knew that Lin Yunwen estimated that the pressure was too great, so he would have the unusual reaction just now, it is estimated that he had been looking for an excellent stainless steel material, and the hope was disappointed again and again.

"Expert Lin, do you still want to conduct a mechanical performance test?" Wang Xudong asked with a smile.

Since this stainless steel material is so good, Lin Yunwen wants to see it with his own eyes, and Xu Jiaxiang is the same, the two nodded almost at the same time, "It would be better to witness the mechanical strength of this stainless steel material with your own eyes." ”

So, a series of mechanical performance tests began, and as soon as the results of each test came out, there were always exclamations one after another, which were either sent by Xu Jiaxiang or by Lin Yunwen, and the two were really shocked.

As one test after another, the two became more and more shocked, and even to the final numbness, the two never thought that in our country, such a good stainless steel material was born.

Witnessing the completion of this series of experiments, the flush of excitement on the faces of the two did not fade, and Lin Wenyun was even more joyful and excited.

No, he held Wang Xudong's hand tightly and said loudly: "Mr. Wang, thank you so much, our model of aero engine will be successfully developed in the future, and you will make a lot of contributions!"

With such a good stainless steel material, the two major material problems faced by Lin Yunwen have been successfully solved and half of the success has been solved.

In addition to being happy, Lin Yunwen also told the truth, his face changed, and he sighed slightly, "It's a pity, there is still a big problem, the problem of superalloy materials has not been solved." If we can solve the problem of superalloy materials, I am sure that this aero engine can be developed successfully. ”

Wang Xudong asked: "Expert Lin, what superalloy material, can you tell us, maybe, our Sanlian Special Steel can solve it for you, Lao Chen, isn't it." ”

Sanlian Special Steel has just been established, need to make a reputation, if it can solve the key material problems of the national key model of aero engines, the fame will not be said, maybe it can be listed at the top level, which is only good for the future development of Sanlian Special Steel.

Chen Sanlian was stunned for a moment, and thought in his heart, Sanlian Special Steel can smelt this super stainless steel is very remarkable, where can it smelt any superalloy materials, however, Chen Sanlian thought about it again, and thought that the whole set of smelting methods for this super stainless steel material Wang Xudong took it out, and suddenly, Chen Sanlian nodded vigorously and said loudly: "Yes, our Sanlian Special Steel has this technical strength, what superalloy or something, a piece of cake." ”

Cow, or you old Chen Niu!

Wang Xudong said in his heart that he was already a little pretending to be forced, but he didn't expect Lao Chen to be so old and more angry than himself in terms of pretending to be forced.

Seeing Wang Xudong looking at himself like this, Chen Sanlian thought in his heart, am I pretending to be a little forced.
