Siheyuan: The Era of Struggle

Chapter 191 Research and Development of High Temperature Resistant Materials (Subscription Request)

With the arrival of Mr. Ye and the researchers from Shu Province who were studying heat-resistant materials, Yang Ning, in addition to processing the data sent to the Data Processing Institute, went to the Metallurgical Research Institute with Mr. Ye and others to engage in the research of high-temperature resistant materials.

For aerospace engines, the parts with the highest material requirements are high-temperature areas such as turbine engine blades, combustion chambers, and exhaust nozzles.

The combustion chamber and exhaust nozzle parts can be solved with the titanium alloy we developed before, but for a rocket missile that will only be used once, using titanium alloy is a bit too extravagant.

Although we have now solved titanium alloy technology, it does not mean that titanium alloy is cheap.

As for turbine blades, the requirements for materials are even higher, because it not only requires the material to have good high temperature resistance, but also requires it to have super strong tensile strength.

Because Mr. Ye and his team had previously studied aircraft engines, they directly used titanium alloys for combustion chambers and exhaust nozzles, so their main research was on turbine blade materials.

Because Mr. Ye and his team already had technical accumulation in the area of turbine blades, after discussion, they decided to first tackle the material of turbine blades.

"Yang Ning, what do you think?"

At the seminar, Mr. Ye, the project manager, looked at Yang Ning and asked.

In the past two days, after Mr. Ye handed over their previous research materials to Yang Ning, Yang Ning has been busy studying these materials.

After he finished studying the information, Mr. Ye, who got the news, held this seminar to see whether their previous research was correct.

"Mr. Ye, I've looked at your previous research materials these past two days. Your previous research was mainly based on Big Brother's GH3030 nickel-based deformable high-temperature alloy. The best performance can only meet the requirements of stable operation under turbine inlet temperature below 800℃?"

"That's right!" After hearing what Yang Ning said, Mr. Ye nodded and said, "That's true. This alloy is already the best high-temperature resistant alloy we can get."

"However, this performance is good enough to meet the requirements of the J-6 engine, but it is still a little short of the power requirements of the dual-class fighter."

This year, under the guidance of our big brother, we produced this alloy for the first time. Unfortunately, this alloy is outdated for our current needs and can no longer meet the power requirements of our missiles and dual-war fighters.

Even so, we still cannot refine this alloy ourselves without the guidance of Big Brother's experts.

In other words, the previous research by Mr. Ye and his team only solved the problem of independent production of our GH3030 nickel-based deformable high-temperature alloy, which was not of much help to the current missiles and the engine of Fengfei.

There is no other way. If we want missiles and aircraft to fly at a speed of more than Mach 800, a turbine inlet temperature of only 900°C is not enough. The temperature must be raised to at least °C.

Unfortunately, Big Brother won’t give us the technology to produce materials that can meet this performance requirement right now.

This is also a helplessness in the field of high-temperature resistant materials. There is no way. Research in the field of materials is like this. Even in later generations, the development of high-temperature resistant materials is still not very fast.

After seventy or eighty years of development, even when Yang Ning traveled through time, countries around the world had only improved the high temperature resistance of materials by less than 100°C. As for the fact that the inlet temperature of some engine turbines has reached 2000+, it was only because scientists saw that the temperature of the materials could not be raised any higher, so they adopted many cooling technologies for the turbine blades to achieve this.

Big Brother's high-temperature resistant material technology that can increase the turbine inlet temperature to over 900°C is their core secret now. This material will be the key for Big Brother to maintain its air superiority for a long time to come. How could they possibly give it to us?
"Does that mean we have mastered the formula and smelting process of GH3030 nickel-based deformable high-temperature alloy? And the problem of mass production has been solved?"

After hearing what Mr. Ye said, Yang Ning hurriedly asked.

As long as we can manufacture GH3030 nickel-based deformable high-temperature alloy ourselves, there will be no equipment and process obstacles for the high-temperature resistant materials that Yang Ning will talk about next.

Because the alloy that Yang Ning knew was a new type of high-temperature resistant material that we developed in later generations based on the GH3030 nickel-based deformable high-temperature alloy given to us by our big brother.

This material simply reduces the nickel content in the GH3030 nickel-based deformable high-temperature alloy formula, reducing the nickel content from more than 50% to about 40%, and then adjusts the proportion of some other materials.

Just this one adjustment has increased the turbine inlet temperature of our engine from less than 800°C to over 1000°C, and the equipment and processes used have remained almost unchanged.

So Yang Ning took out the formula he had compiled and said, "This is a new formula that I simulated and calculated these two days based on your previous research data. I just adjusted the proportion of some materials in the GH3030 nickel-based deformable high-temperature alloy. I simulated that the high-temperature resistance of this new alloy is better than the previous alloy. As for the specific situation, we need to burn it out and test it before we can know."

"Oh, you have an idea so quickly?" Old Ye was also surprised by Yang Ning's speed this time. He took the formula from Yang Ning's hand and started to look at it.

However, the material field is different from other fields. You can’t tell anything from the data. Whether something is good or not can only be known after it is burned and tested.

“The proportion of nickel has dropped by about 10%, and there are no other precious materials.”

"Let's not talk about other things. Just based on this point, as long as the performance is not worse than GH3030 nickel-based deformable high-temperature alloy, it is a great improvement. At least it can save a lot of costs." Mr. Ye said happily after looking at it for a while.

"Really?" At this time, a researcher from Shu Province heard the conversation between Mr. Ye and Yang Ning and couldn't help asking.

“Haha~” Seeing that everyone else looked skeptical, Mr. Ye smiled and said, “If it were anyone else, I might think this was nonsense, but Comrade Yang Ning is not necessarily the case. As long as it is something he takes out, I have never seen it fail.”

Since Yang Ning has already come up with the recipe, we have to try it no matter what.

Although Mr. Ye was full of confidence in Yang Ning's recipe, he was still a little nervous before the finished product was cooked.

So, as soon as the meeting ended, Mr. Ye immediately organized people to burn a batch of finished products according to the recipe given by Yang Ning.

Two days later, before Yang Ning had finished his work at the data processing office, Mr. Ye came to him in a hurry with the test data report of the high-temperature resistant metal fired with the formula provided by Yang Ning...
