Naturally, Cao Weidong in this life does not recognize the person in front of him.
But he was very familiar with it in his previous life.
Whether it is in movies, TV shows, or in various textbooks, he is everywhere, and he is described vividly.
He is the world's top scientist, aerodynamicist, and the founder of China's manned spaceflight!
At the same time, he is known as the "Father of China's Scientific System" and the "King of Rockets".
And one of the founders of two bombs and one satellite.
The famous Dongfeng Express in the previous life is inextricably related to the person in front of me.
Mr. Qian!
Cao Weidong's eyes were filled with respect.
Because I was too surprised, I blurted out the other person's name. When I realized it, I suddenly felt a little reckless.
After all, there is no intersection between myself and Mr. Qian in this life.
Faced with Mr. Qian's inquiry, he was quick to think and said.
"You once gave a speech at the university. I went to listen to the speech with my friends. Your speech inspired me a lot. From then on, my wish was to become a scientist."
Mr. Qian touched his head and asked doubtfully: "Is that so?"
Cao Weidong became more and more compliant with his words and continued to make up random things.
"Yes, after I went back I asked my father to find the newspaper you wanted to close. Your photo was on it, so I recognized you as soon as I saw you. My neighbors all remembered it."
Cao Weidong's father has long since died, and he is not afraid that Mr. Qian will investigate.
And given the character of the neighbors in the courtyard, most likely they would not be able to remember such trivial matters.
Quite the opposite.
If it is a trivial matter such as the owner of the family is short of family, or someone owes someone a few buns.
No matter how much time passes, they can recall it accurately.
Seeing what Cao Weidong said so confidently, Mr. Qian believed it eight or nine times.
After returning to China, he attracted attention from all walks of life and was invited to give some important speeches.
It is normal for the other party to have met you through some public channels and recognize you.
At this time, the old man in military uniform said.
"Haha, since you know each other, that's great. I don't understand what you scientists are talking about. I'll ask the logistics department to prepare lunch, and we'll have it here at noon."
Mr. Qian said thank you.
He and Cao Weidong sat down separately, and he introduced a few assistants who were with him.
Then Mr. Qian changed the topic.
"Since you know me, I won't waste any more words. In fact, I am currently conducting a very important research, but because the metal quality is not up to standard, the research ultimately failed, so this time I came to Sijiu City for
Looking for the right steel."
"I just happened to hear from Minister An of the Ministry of Metallurgy that you successfully extracted rare metals and created an alloy called memory metal. I was very curious, so I asked someone to find you."
"Can you introduce me to memory metal."
When Cao Weidong heard what Mr. Qian said, his mind was spinning rapidly.
If I remember correctly, China’s first short-range missile, Dongfeng-1, was successfully launched about two years ago.
By this time, Mr. Qian should be conducting research on Dongfeng-2.
Wait, it’s April now...
Cao Weidong's mind was spinning rapidly, and relevant memories emerged.
He vaguely remembered that the research on Dongfeng-2 finally ended in failure, and it was during this period.
Either in February or March.
As for the reason...
It seems that because the range of Dongfeng-2 is twice that of Dongfeng-1, the gunpowder carrying capacity is also much higher, which places high requirements on the structure and seismic strength of the projectile.
However, the materials used to make Dongfeng-2 did not meet the standards, and the relevant structures were displaced during the launch of the missile, which led to the failure of the research.
Perhaps it was for this reason that Mr. Qian came to the Ministry of Metallurgy for help.
Mr. Qian is a great man who has been forging swords for the country throughout his life.
As he once said.
You can use this sword, but you can’t live without it.
The experiences of many countries in previous lives have confirmed Mr. Qian’s words.
A country without a sword can only be harvested by others.
Therefore, Cao Weidong only has admiration for Mr. Qian, so how can he dare to hide anything?
He started with the slag he obtained for smelting iron ore in Wan'an County, and told the whole process of smelting memory metal.
Of course, there are sufficient modifications and beautifications.
Mr. Qian sighed.
"In other words, you only think about recycling waste at first, but you accidentally discover a treasure. It's really amazing."
He praised Cao Weidong very much.
Perhaps out of the desire to test his teaching skills, or simply for academic exchange, Mr. Qian asked again:
"So how do you smelt this kind of memory metal? What is the quenching process, temperature control, and heat treatment process?"
"Well, I have improved the blast furnace and adopted a special high-temperature tempering process. The main components of the memory alloy are nickel and titanium. After the test, the ratio is about 37. The heat treatment process I chose is..." Cao Weidong responded fluently.
By the way, I talked about a lot of alloy knowledge that was developed in my previous life.
The more Mr. Qian listened, the more horrified he became.
Because some of the knowledge in it requires even yourself some time to digest it before you can understand it.
He asked in shock.
"As far as I know, you didn't graduate from a major, so you taught yourself all these things?"
Cao Weidong said.
"Yes, I did not take the college entrance examination. Later, due to some reasons, I went directly to the steel rolling mill. I also watched and learned in the steel rolling mill, and finally figured it out by myself."
Mr. Qian slammed the table and praised him repeatedly.
"This is the attitude that young people should have. Learn at work, grow while studying, and do both work and study."
He looked at the young cadres beside him and sighed.
"Although you have graduated from a major, you lack Comrade Cao Weidong's attitude of studying. You should learn more from others."
These young cadres can serve as assistants to Mr. Qian. They all have extraordinary backgrounds and are extremely knowledgeable.
They were a little arrogant at first.
I think Cao Weidong just got lucky and got the memory metal by accident.
But when they heard Cao Weidong's explanation, they realized that it contained a lot of knowledge, which could not be described by a simple sentence of luck.
An assistant raised his hand and asked respectfully: "Teacher, I don't understand the heat treatment process you just mentioned. Could you please explain it again."
Cao Weidong felt extremely beautiful.
The people around Mr. Qian put him down regardless of their academic qualifications, resume or age.
But now I can only call myself teacher.
Of course, this does not mean that I am better than Mr. Qian.
It can only be said that there are specialties in the art industry.
Moreover, he has a portable space to cheat, and has forged so many rare metals with his own hands. His knowledge in metallurgy is more advanced and systematic.
If you reveal it a little bit, it will be enough for these people to study it for a long time.
He explained a little bit, then took out the memory metal he had prepared in advance from his backpack and asked Mr. Qian to check it.
"So this is memory metal?"
Mr. Qian tried the shape memory function of the memory metal, and then asked his assistants to test the memory metal with instruments.
The conclusion is that the strength and toughness of this metal far exceed that of existing domestic metals.
Mr. Qian was amazed.
Although this kind of memory metal is not the type he is looking for, its unique characteristics can still be applied in many aspects.
Cao Weidong said: "Although I don't know what research you are currently conducting, it is definitely beneficial to the country and the people. I am willing to hand over the smelting formula to you, and I will write it down for you later."
Mr. Qian held Cao Weidong's hand and said gratefully.
"Comrade Cao Weidong, thank you."
"To be honest, memory metal is quite magical. Although it cannot solve the direct problems we face, it can iteratively replace many parts, which is also a pretty good harvest."
Cao Weidong asked curiously.
"I wonder what kind of metal material Mr. Qian is looking for?"
Mr. Qian stated his request.
The first requirement for the metal he is looking for is high temperature resistance.
Secondly, it must have strength and toughness beyond ordinary metals.
Mr. Qian sighed.
"Hey, I know this is not easy. We have been searching for a month, from south to north..."
Cao Weidong said: "I have."
Mr. Qian said minding his own business.
"I know you do, but it's really difficult. After all, considering the current metallurgical level in the country..."
He suddenly reacted.
His eyes widened and he asked stammeringly.
"What, you have?"
Cao Weidong smiled and said: "Yes, in the process of developing memory metal, I accidentally obtained the metal formula of a titanium alloy. According to research, this metal has excellent high temperature resistance, corrosion resistance, and is of high quality.
Light, it may meet your needs."
Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. From this aspect, it is indeed in line with Mr. Qian’s expectations.
Mr. Qian said in surprise.
"Titanium alloy?"
China is a country with large reserves of titanium, and research on titanium alloys began in the 1950s.
When Mr. Qian encountered a material bottleneck, he immediately thought of titanium alloy.
However, this kind of titanium alloy is too scarce.
And things are valuable when they are rare.
In this era, titanium alloys can even be measured with the equivalent of gold.
Therefore, although titanium alloy meets the standards, it does not meet the conditions for large-scale application.
Cao Weidong said: "Your concern is mainly about output. There are many associated titanium ores in the mines near Wan'an County. Through research, I invented a new smelting method that can purify pure titanium at a lower cost." "As for this titanium alloy, now that we have the formula, it is simple."
He took out another titanium alloy from his backpack and handed it to Mr. Qian.
Mr. Qian took it, took the initiative to ask the assistant for the instrument, and tested it himself.
Soon, the test results will be released.
Looking at the exaggerated numerical results, Mr. Qian's hands were trembling with excitement.
There is really no place to hide even if you have worn iron shoes, and it takes no effort to get there.
At first, he just heard that a young man accidentally invented an interesting functional metal. Out of curiosity, he asked the head of the military region to find the young man.
As a result, the young man gave himself surprises one after another.
He put down the titanium alloy, looked at Cao Weidong, and made a serious proposal.
"Comrade Cao Weidong, I wonder if you are interested in joining my research? I would like to invite you to be my deputy."
