Titanium alloy has extremely strong tensile properties. According to the surface data of the world's laboratories, the maximum tensile strength can reach 1764Mpa. However, this is a combination of titanium and other precious metals. For large-scale use, the cost is too high and there is not much promotion value.
Otherwise, with a fighter jet of that size, and built with precious metals that are much more expensive than gold, no economy, no matter how large, could afford such consumption.
Currently, the most advanced aviation material is titanium-aluminum alloy. Aluminum is relatively cheap, and its large proportion makes it more economical and practical. However, the inclusion of large amounts of aluminum naturally reduces the density of titanium, making it difficult to have your cake and eat it too. Currently, the highest tensile strength of commercially available titanium-aluminum alloys is only 400-700 MPa.
Wu Tong's material model is built on this foundation, deducing a more superior molecular structure, a more superior material ratio, and combined with innovative technology, ultimately achieving an ultra-strong titanium-aluminum alloy material with better tensile properties, creep resistance, oxidation resistance, and higher tolerance.
The data deduced in advance flew across Wu Tong's fingertips and was input into the laboratory computer, while Ruan Chengxu watched from the side.
"Ti--6Al-zi..."
As Wu Tong delved deeper into the data, Ruan Chengxu looked at the gradually taking shape of the molecular structure, his expression growing increasingly solemn. This structure? It seemed like he had never seen it before!
It is completely different from the common titanium aluminum alloy molecular structure today!
Interesting! Cheng Huanan walked in slowly, holding his chin with his hand. His expression was exactly the same serious as Ruan Chengxu's. Compared to Ruan Chengxu's keen sense of something wrong, he saw something much broader!
Wu Tong's first material work was perhaps more surprising than he expected.
It seems that his future closed disciple prefers pioneering and innovative ideas rather than following the routine and introducing new things!
After Wu Tong entered the last piece of data, Cheng Huanan reached out and clicked the confirmation button to confirm the simulation calculation of the theoretical properties of the material.
Soon, the software began to run the data and, based on the perspective of molecular dynamics, began to calculate the theoretical mechanical properties of the target material at a macroscopic level.
The computer computing power in the laboratory is quite good, and soon the theoretical test results were displayed on the screen.
1270MPa? ·····
Ruan Chengxu's eyes widened in surprise, staring at the theoretical tensile resistance data displayed on the screen in disbelief. Was he dazzled, or was the system malfunctioning?
Because of the high proportion of aluminum, the density of titanium is diluted. The general data that titanium-aluminum alloys can currently achieve is around 600 to 700, which are all excellent materials and are highly sought after in the aviation industry.
And now...
Ruan Chengxu rubbed his eyes. It was still the same 1270MPa. Wu Tong's simulation data had doubled this general threshold!
What is the concept?
If this data is true, it will immediately break the world record and become national strategic confidential material. They need to report it immediately, dispatch protection forces, and sign a confidentiality agreement for operation.
Compared to Ruan Chengxu's surprise, Cheng Huanan was much calmer. His eyes moved between the data on the screen and Wu Tong's manuscript, comparing and arguing.
After a while, he finally spoke, "The data you imported wasn't originally deduced, right?"
"I just had some sudden inspiration and made some appropriate adjustments!" Her previous model was only based on her preliminary understanding of materials science. In the past two days, she has done a lot of research on this aspect. In addition, she has just visited the laboratory and learned about various instruments and processes... Her absolute judgment has become more accurate, which has led to this version with more practical data.
"Mr. Cheng, can you help me see if this material is worth investing in experimental preparation?" Wu Tong smiled embarrassedly. She did some deductions on a whim and asked Dean Pan to help connect with her, so she came to Mr. Cheng's laboratory.
She hadn't thought much about it before, but now she suddenly realized whether the country has similar materials of this strength. If so, her deduction is just for her own entertainment and there is no need to continue.
"Just look at your senior brother's expression and you will know whether it is valuable or not!" Cheng Huanan pointed at his disciple Ruan Chengxu who was looking surprised. He still had little experience and lacked the composure to remain calm even under pressure.
However, Wu Tong's simulation results were so outstanding that even this old man felt that he had seen the world.
He thought Wu Tong was just a beginner, and that being able to design materials and make shapes was a talent. If he could improve and progress, he would be a top genius. Who would have thought that Wu Tong would directly give him a result that was beyond his reach?
As expected, he is a child who is good at creating miracles.
"It's absolutely necessary!" As for the materials, there is a 10% chance that they will have to be tested day and night, not to mention that Wu Tong already has the detailed requirements.
Ruan Chengxu covered his face with his hands, he was purely being shown off by the big guy, his momentary thoughts were mostly rubbish, my god's momentary thoughts were that it would directly catch up with the UK and the US, and take the lead in the world!
"Go and arrange the material preparation, and all expenses will be paid from the laboratory account!" Although there are often big differences between simulation results and experimental results, the difference will not be too excessive if the data is detailed.
Wu Tong's simulated pouring model data is detailed enough, the molecular structure of the material is also very interesting, the material ratio and the selection of preparation process are very detailed, and the result is very likely to be successful...
Then there is no need to say more, just get to work and experiment to find the truth.
As the leading materials expert in China, Cheng Huanan knows more and understands better what it means if this material can really be realized!
As long as the actual value of the material is 60% of what Wu Tong simulated, he will directly help Wu Tong write internal references, help Wu Tong establish projects, and assist Wu Tong in moving the material from the laboratory to production.
Sixty percent of 1270MPa is more than 760MPa, which exceeds almost all titanium-aluminum alloy materials currently available. It is enough to become the newest and most excellent aviation material choice. Even if the experimental results are even better, it can definitely be used on the blades of the current new generation of turbofan engines, allowing the country's highly anticipated J-20 to take a big step towards super-performance test flight and takeoff.
He's currently involved in research on the WS-15's blade materials and is still trying to find optimal solutions. He has the data in his head, and by comparison, Wu Tong's current simulations clearly outperform.
Cheng Huanan laughed. If he remembered correctly, the kid's original purpose in designing the material model was for fighter plane body materials!
The leap from fuselage materials to core fan blade materials is enough to make most materials scientists ashamed and angry! If their country's fuselage materials were configured according to this ratio, would they still be worried about the beyond-visual-range Raptor across the sea?
He hoped more than anyone else that this material simulation could become a real thing! Cheng Huanan's heart seemed to return to the anticipation and excitement of his first successful material preparation in his youth.
