These two people are not simple, they are both senior experts, one is a senior expert in the field of materials, and the other is a senior expert in the field of aero engines. Pen, fun, and www.biquge.info

As a senior expert in the field of Huaxia aero engine, Lin Yunwen is presiding over the development of a national key aero engine.

The progress of this aero engine at the beginning is still good, not only successfully completed the design, but also has completed the trial production of the first verification machine, this verification machine also went to the test bench for testing, however, from the test situation, it is not ideal.

After careful analysis by the entire scientific research team, the problem is not in the design, nor in the manufacturing process, but in the material.

Taking advantage of his friend Xu Jiaxiang's birthday this time, Lin Yunwen specially took the time to come over and congratulate Xu Jiaxiang on his fiftieth birthday, which is one aspect, and the other aspect, which is the most important, Lin Yunwen wants to seek Xu Jiaxiang's help.

It's a pity that Lin Yunwen said the situation, Xu Jiaxiang also felt very brainless, and helpless, this is a key model of aero engine, the requirements for materials are very harsh, even Xu Jiaxiang, there is no way to solve this material problem.

Lin Yunwen's heart was full of disappointment, and now he was slightly depressed, ready to leave Jiangnan Province, and continue his research after going back, Lin Yunwen even had such a plan, he really couldn't solve the material problem, so he could only change the design structure and reduce the requirements, but in the same way, the overall performance of this aero engine will drop a lot.

Helpless, there is no way, it seems that the overall performance of the aero engine can only be sacrificed, Lin Yunwen thought so frustratedly.

Wang Xudong heard the content of the chat between the two clearly, Wang Xudong turned around and looked at these two people curiously, Wang Xudong saw that Xu Jiaxiang gently patted Lin Yunwen's shoulder, which was considered comfort, and then sighed softly.

Wang Xudong is moved, he is one of the shareholders of Sanlian Special Steel, although he is standing behind the scenes, but if he can bring customers for Sanlian Special Steel, especially military customers like this, if Sanlian Special Steel's special steel can be purchased by the military and used in military products, it is a great thing.

Domestic aero engines, eight or nine out of ten are used by the military, that is to say, if the special steel of Sanlian Special Steel can be used in aero engines, the heaviest user is the military.

Wang Xudong wanted to say loudly, I can solve your problem, but Wang Xudong knows that if he really says this, the other party will not believe it or not, and it is estimated that he may think that he is crazy.

Knowing this in his heart, Wang Xudong was very strategic, looked at the two with a friendly smile, and accosted: "You are experts, you invite first, we are not in a hurry." ”

There were more people checking in, and Wang Xudong's team lined up several people, and Lin Yunwen and Xu Jiaxiang were behind Wang Xudong.

Lin Yunwen said: "Young man, it doesn't matter, come first and come first, or you first." ”

Wang Xudong has a good impression of Lin Yunwen and Xu Jiaxiang, and the two see that Wang Xudong is young and polite, and they also have a good impression of Wang Xudong.

Just now, when the two were chatting, they paid great attention to confidentiality, and it is estimated that they knew that this was a public place, and when they talked about it, they only mentioned at most what key models, what aero engines, and words such as encountering trouble, and never mentioned materials, aero engine models, verification test details, etc.

However, Wang Xudong guessed that the two of them estimated that they had difficulties in transporting materials, and Sanlian Special Steel should immediately open the furnace to smelt the first furnace of super stainless steel, and Wang Xudong wanted to sell it to the two.

Wang Xudong is really crooked.

Wang Xudong said: "Two, Wujiang City's Sanlian Special Steel Group, is about to smelt the world's most advanced super stainless steel, which is a very remarkable stainless steel material, not only corrosion resistance is absolutely first-class, but also has good mechanical processing performance, super mechanical structure strength, I don't know if you two are interested?"

Lin Yunwen's eyes lit up, but soon his eyes dimmed, he sighed slightly, and thought in his heart, Sanlian Special Steel, I have never heard of it at all, and it is estimated that this so-called super stainless steel is not much better, so don't hold up hope.

Lin Yunwen presided over the research and development of this aero engine, and there are two major material problems, one of which is the problem of stainless steel materials.

Generally speaking, titanium alloy materials are widely used in the compressor part of aero engines, because this material is corrosion-resistant, has a small specific gravity, is light and has high mechanical strength, and is the preferred material for cold parts such as compressors.

But titanium alloy is not perfect, there is a fatal shortcoming, that is, it is not resistant to high temperature, to improve the overall performance of this aero engine, in the design to improve the compression ratio, the compression ratio is high, the compressor compressed air level by level, with the compression of air in the compressor level by level, the temperature is also increased level by level, the temperature of the compressor after several levels is hundreds of degrees, beyond the limit of titanium alloy, stainless steel materials must be used.

High-quality stainless steel materials are also corrosion-resistant, and also have very good mechanical strength, the only point is that the proportion is a little bigger, in order to improve the compression ratio, in order to improve the overall performance of the engine, although the stainless steel material has a little more weight, but compared with the overall performance improvement, it is completely worth it.

Of course, the material problems encountered by this new aero engine are not only stainless steel, but also a high-temperature material, but if any of them can be solved, it will definitely be a huge surprise for Lin Yunwen.

It's a pity that Lin Yunwen didn't believe it, and he didn't believe that the Sanlian Special Steel, which he had never heard of, could develop stainless steel materials that met the needs of advanced aero engines.

Aero engines, especially advanced aero engines, are very demanding on materials, Lin Yunwen knows.

Wang Xudong saw that Lin Yunwen didn't believe it, so he just shook his head lightly and didn't continue to chat, Wang Xudong's meaning was obvious, I have already given you the opportunity, you don't believe it yourself and lose this opportunity, that's your own problem.

"Brother Dong, it's our turn. ”

Liu Yu shouted in front, Wang Xudong smiled, and did not talk to Lin Yunwen anymore, but took a few steps forward, began to help Zheng Xiaotong check in, get the boarding pass, and the three of them walked towards the waiting hall together.

Walking to the door of the waiting hall, Zheng Xiaotong was obviously reluctant, because they were about to separate, Zheng Xiaotong wanted to return to the capital, and the two would not see each other again for at least a week.

"Tung Brother ......"

Zheng Xiaotong's eyes suddenly turned red, and big tears were about to flow down, looking pitiful, and Wang Xudong was very distressed.

Wang Xudong gently hugged Zheng Xiaotong and kissed Zheng Xiaotong lightly on the forehead, who knows, Zheng Xiaotong reacted hugely, and took the initiative to kiss Wang Xudong in his arms.

There are many people at the airport, if it is usual, according to Zheng Xiaotong's character, he will definitely not take the initiative to kiss Wang Xudong in such a place, but thinking that he is about to return to the capital, after going back, he still doesn't know what kind of attitude the family has towards his future marriage, whether he will accept Wang Xudong or not, Zheng Xiaotong has no bottom in his heart.

Zheng Xiaotong knows that his father has a good impression of Wang Xudong, but in addition to his father, his mother obviously doesn't like Wang Xudong, and in addition, the Zheng family is such a big family, which is not as good as ordinary people's families, and other people's attitudes.

What's more, Zheng Xiaotong also knows that his grandfather has not said anything so far, although he has no objection, but he has not said that he supports it, if his grandfather does not support him and Wang Xudong together, then what should I do.

It is precisely because of such various concerns in his heart that Zheng Xiaotong's reaction is so huge, Wang Xudong seems to understand, and in addition to being moved in his heart, he secretly said that no matter how much resistance he encounters, he must be Xiaotong together.

The two kissed each other for a long time before parting, Liu Yu was very conscious, dragging his suitcase, he had already walked far away, watching the scenery at the window in the distance, and looking at the planes parked on the airport through the glass of the window.

Zheng Xiaotong said with red eyes: "Brother Dong, no matter what, we must be together, and we will never be separated, okay." ”

Wang Xudong nodded firmly and said: "Well, no matter who we are, after the New Year, I must come to the capital, I want to propose to the Zheng family, I want to marry you." ”

After receiving Wang Xudong's firm answer, Zheng Xiaotong was moved, and in Wang Xudong's arms, he wiped his tears and burst into laughter.

Wang Xudong gently touched Zheng Xiaotong's hair, and said lovingly: "Little fool, the plane is about to take off, you go in quickly, when you get to the capital, call me." ”

"Hmm. Zheng Xiaotong nodded.

………

Lin Yunwen also checked in, because it was still early before the boarding time, Lin Yunwen and Xu Jiaxiang were chatting, and they had not yet entered the waiting hall.

Lin Yunwen said: "Lao Xu, that young man just now is really strange, what do you say about Sanlian Special Steel, what super stainless steel, I don't believe it, it is estimated that it is just ordinary stainless steel, and it is just a big road." ”

Xu Jiaxiang nodded and said, "I guess it's the same." ”

The two chatted, and after chatting for a few words, Xu Jiaxiang suddenly seemed to remember something, and after being stunned, he suddenly said: "Lao Lin, I remembered this Sanlian Special Steel, I have a friend, Ding Huixian, do you know, he went to this Sanlian Special Steel." ”

Ding Hui is a metallurgical expert first, and he has also made a super strong steel and won the National Science and Technology Progress Award, plus Ding Hui is a native of Jiangnan Province, and Xu Jiaxiang is also from Jiangnan Province, the two have known each other for a long time, and the relationship is not bad.

A metallurgical expert, a material expert, metallurgy and materials are closely related, Xu Jiaxiang and Ding Huixian have a good relationship is completely normal, not long ago, the two even met for a meal, Ding Huixian said that he went to Sanlian Special Steel, as the chief expert of Sanlian Iron and Steel, Xu Jiaxiang was taken aback at that time.

Now that I think about it, Sanlian Special Steel is the steel company where Ding Huixian served as the chief expert, and suddenly, Xu Jiaxiang was inexplicably excited in his heart, and he had a hunch in his heart, it is estimated that this super stainless steel is really not simple.

With a slightly excited tone, Xu Jiaxiang said: "Lao Lin, hurry, don't take the plane to rush back, let's hurry up and find the young man just now, hurry!"
