Chapter 213
Everyone has a proud look on their faces.
This space elevator project is not only done by moving mountains and reclaiming the sea, but also involves countless organizations and industries. And this is a test of a country’s comprehensive scientific and technological strength.
If it is replaced by any other country, it is estimated that this space elevator will not be built by moving mountains and reclaiming the sea…
Without him, the comprehensive scientific strength of some countries is too low.
The ability of some countries to coordinate operations is too low. Do not cooperate with each other.
But here, various agencies and departments are proud to participate in the space elevator project.
Li Qi did not step up to the main stage, but just stood in the aisle of the conference room to speak:
“A building in the lower district is not qualified to be above the experts, so I won’t be on the stage to speak. Right here, we will quickly discuss and solve the problem.”
Everyone laughed kindly.
It doesn’t matter whether Li Qi is on stage or not. After all, they are mainly rushing to solve problems.
However, the absence of Li Qi02 left a very good impression. Young people are neither arrogant nor arrogant.
Li Qi said solemnly:
“Time is tight and the task is heavy, so I won’t be too nonsense. I came here on behalf of Yishan Reclamation, hoping to solve the most critical part of the space elevator-the material problem. The kid doesn’t have much research on the mechanics of materials. , I hope you can show me a clear way.”
When the voice fell, an expert who kept the eight-character Hu smiled and said:
“Knowing that you are coming, knowing that you are short on time. So we will discuss it in a small way. Before you come, we have listed a total of 20 aerospace materials. The characteristics of various materials have been listed, let’s just Discuss which one to pick?”
Li Qi’s eyes lit up: “This is the best way.”
Ba Zi Hu didn’t talk nonsense, and stepped onto the podium: “Thank you to turn on the projector.”
With a ‘click’, the lights in the conference room went out, and a projector appeared on the podium.
Eight-character Hu Shen said:
“Aluminum alloy. Light texture, high strength, corrosion resistance, and high weldability. But the disadvantage is that it is not resistant to high temperatures, which is also its advantage and has strong plasticity.”
Li Qi listened quietly, without commenting.
Su Mingyu said solemnly: “This is eliminated. It is not resistant to high temperatures… It has no way to hang down from space at all. When passing through the atmosphere, it melts itself away.”
Ba Zi Hu continued:
“Titanium alloy, this one has high heat resistance. It has high strength…”
Su Mingyu sighed again: “But it’s high in quality. If it’s high in quality, it’s destined to go to heaven…”
Li Qi answered:
“Should I talk about the request, let’s exclude some metal first?”
“You speak.”
“We need strong toughness, high hardness, light texture, corrosion resistance, high temperature resistance…”
The voice fell, and the audience was silent. Everyone was dumbfounded, not knowing what to say.
You… This is the advantage of all metals!
Where can there be such materials? To have such materials, China’s aerospace sciences has surpassed the United States for two fifty years.
Eight-character Hu gave a wry smile: “Mr. Li, it seems that you really don’t understand material science.”
Li Qi blushed and said, “Ah… I don’t understand. Are these conditions difficult to achieve?”
“It is not difficult to achieve, it is impossible to take into account at all. Each material has the characteristics of each material. But if you want to take into account, you need an alloy. And alloys also have different characteristics, but the characteristics are not infinitely powerful. This There is no omnipotent material in the world. Do you understand if I say that?”
“I can understand…”
Li Qi sighed: “However, the first heavenly metal’wire’ we need, it must be light in weight, strong in endurance, and strong in tension.”
“If you say that… since it is the first one to go to heaven, the corrosion resistance and high temperature resistance, in fact, we can weaken it as appropriate.”
Li Qi looked at Su Mingyu for advice.
Su Mingyu thought for a while and said:
“The first one to go to the sky is actually just used as a bridge. I personally think that this temporary bridge built is enough for it to cross the river. Corrosion resistance can be removed, but high temperature resistance is a must. There must be one thing that is tensile strength!”
Ba Zi Hu pondered for a long time:
“If you want to say that, then, magnesium alloy!”
magnesium alloy?
Li Qi murmured: “Then this magnesium alloy, how strong is its bearing capacity? Our main consideration is still bearing capacity. Without bearing capacity, everything is just empty talk.”
“The ability to bear is a little worse than steel. But it’s quite enough…”
Almost better than steel?
That won’t work…
At this moment, a young man who appeared to be born in 1995 stood up and shouted:
“I see.”
Li Qi quickly looked at him: “Little brother, please tell me.”
“Aluminum-magnesium alloy!”
“High strength, low density, high temperature resistance, and strong tensile strength. If you have to have a metal with such characteristics, I think only aluminum-magnesium alloys!”
Aluminum-magnesium alloy……
The eight-character murmured, his eyes lit up.
And Su Mingyu suddenly raised his eyebrows: “Aluminum-magnesium alloy…Yes, aluminum-magnesium alloy!”
“…”.
