A few days later, in the foreign guest reception room of China Commercial Aircraft Manufacturing Company, Anderson Foggs, the representative of Honeywell International, and Kelly Hall, the representative of Rolls-Royce, were discussing and waiting.

Their purpose is the same, and they are all to sell manufacturing technical information of engine blade materials to Huaxia Commercial Aircraft Manufacturing Company as soon as possible. Both parties are competitors and they are inevitably testing each other and finding each other's bottom line.

"Two, let's wait for you for a long time." Peng Zhengge walked out of the door and said.

"General Peng!" The two stood up and shook hands with him, eager to know the decision of the China Commercial Aircraft Manufacturing Company.

Generally speaking, such things should be discussed separately, because no matter which party you reject, it will hurt people's face. But today Peng Zhengge is not worried about this issue, because he does not need to reject either party, and the other party will naturally understand.

"Before talking about cooperation, I would like to invite two to visit our Aviation Materials Research Institute. Today is the day we will test the latest low-pressure turbine engine blades, so please also visit them together." Peng Zhengge said.

"That happens to be true, I'm very interested, too," Anderson said.

"I am honored." Kelly also expressed his interest.

On the way, Kelly Hall has been emphasizing the importance of their blade material technology with Peng Zhengge.

"Now the aircraft engines we Rolls-Royce for Airbus are all made of this new titanium-aluminum alloy blade. It improves fuel efficiency and greatly enhances the competitiveness of commercial aircraft. Airbus a350-800, a350-900, a350-1000 and a350-900ulr in research and development will all use this blade material to manufacture aircraft engines."

"Airbus relies on this fuel-efficient model to obtain a large number of orders from all over the world, competing with Boeing 787-9 and 777-200er passenger aircraft for the market. If Huaxia Commercial Aircraft Manufacturing Company can use this brand new material and replace nickel-based alloy blade materials, its market competitiveness will definitely be doubled!"

"Mr. Hall is the same as we have considered. Our idea is to use this new material on aircraft engines as soon as possible. Therefore, the aircraft engines purchased also use this new material." Peng Zhengge said.

"Yes." Kelly Hall continued to promote, saying: "If we can cooperate in the manufacturing of this material, your company will no longer have to spend a lot of money on this material, but can make it yourself."

He finished speaking, and Anderson also said: "Our Honeywell Company is willing to cooperate like this."

"Two, after visiting the material testing of the Aeronautical Materials Research Institute, let's talk about this issue again." Peng Zhengge said mysteriously in a tone.

When Anderson heard his tone, he felt a bad feeling inexplicably, just like the large-area molding technology of carbon fiber composite materials before. Could it be that they made it again this time?

Impossible? If Hongxin Group had developed carbon fiber composite materials for the purpose of manufacturing other high-tech equipment, it had long been developed, but this time the materials were only used on aircraft engine blades! It is unlikely that they would have developed technology in advance.

Kelly Hall felt that Peng Zhengge was playing with the mental battle, so as to further compete with Rolls and Rolls and Honeywell International, and lower prices each other.

When we arrived at the Institute of Aeronautical Materials, the manufacturing process of engine blades was underway in the institute.

Zhong Bing, a technical representative of Hongxin Group, said: "The blades rotate at high speed. Any small or hidden metal break marks may cause the blade to break, so the blades must be formed in one piece, and there must be no second or third casting process!"

Gao Wei nodded and said, "We also have an integrated molding design, but there is a problem. In titanium-aluminum alloy, titanium is too active and reacts with almost all metals and ceramics. Integrated molding, a suitable fixed container must be found!"

Zhong Bing carried a spherical quantum computer with him. He opened the projection and said: "Now there are three types of ceramics that do not react with titanium. One is thorium oxide. Thorium is radioactive and cannot be used as a fixed container; the second is calcium oxide, which absorbs moisture and cannot be stored; only yttrium oxide can be used as a fixed container."

"We have considered this too." Gao Wei wondered, "Yttrium oxide is used as a shaped container. Its surface is powdery and it is easy to fall off and contaminate the titanium and aluminum solution, so that the titanium and aluminum blades after forming are not accurate enough."

"That's right!" Kelly Hall happened to hear this and interrupted: "In the German aviation materials laboratory, we used computer simulation to calculate that titanium-aluminum alloy blades longer than 200 mm cannot be formed in one piece. No matter how we do it, we will encounter the problem of yttrium oxide slag loss affecting accuracy."

"That's not necessarily. Computer simulation will also make mistakes." Zhong Bing said.

Kelly smiled and said, "I just reminded that if you fail, we are willing to sell some technical information to help you complete the material manufacturing of titanium-aluminum alloy. As for blades with a length of more than 200mm, I advise you not to waste time."

"What we are going to make today is titanium-aluminum alloy blades that are more than 200mm." Zhong Bing said directly.

Kelly Hall shrugged and didn't say anything, but the expression on his face had already revealed his thoughts, and he was waiting to watch the show.

"Let's start. Prepare titanium-aluminum solution and yttrium oxide solution." Zhong Bing shouted, and the working groups began to take action.

"Mr. Lu, can it work?" Peng Zhengge asked Lu Zixin in a low voice, "Today I called out the representatives of Rolls and Honeywell. If they fail, they will be unable to hold their faces!"

"Don't worry, today, you can see titanium-aluminum alloy blades appearing, and they are definitely more than 200mm." Lu Zixin guaranteed.

There is no problem with titanium and aluminum solution. The most important thing is the manufacturing of yttrium oxide shaped containers! As long as the yttrium oxide shaped container is made and then the titanium and aluminum solution is poured in, it can be formed in one piece.

Gao Wei has always been worried that they have done similar experiments countless times. Every time, they fail due to various reasons, especially the problem of slag drop in the yttrium oxide fixed container, which has caused the accuracy of titanium-aluminum alloy blades to not meet the standards, and they have not found a solution so far.

It is time to make a yttrium oxide shaped container. When smelting the yttrium oxide solution, Zhong Bing asked someone to take a bucket of sealed solution.

"What is this?" Gao Wei said curiously.

"A molecular adhesive, specially used for yttrium oxide, can make its surface smooth and stable without falling off." Zhong Bing said, and someone added the molecular adhesive to the yttrium oxide solution to mold the yttrium oxide shaped container.

Not long after, when the solution cools down, the shaped container appears! Unlike the results of previous experiments, this time, the yttrium oxide shaped container does not appear in surface particles or powdery states, but is as smooth as a mirror!
