"There are classmates of mine at the Shanghai Computer Research Institute. I heard from them that their display screen has been made, but it is just used on computers. I think I can contact them..."

Wang Kun explained the situation, and Yang Xiaotao realized that there was more than one such computer research center in the country.

It is not only available in the Seventh Ministry of Machinery, but also in some universities and research institutes.

It seems that the first calculator of later generations was made in Shanghai.

"You write a report on this matter, and I'll ask someone from the machinery factory to contact you later."

"good."

Wang Kun looked excited. If the display screen is solved, with their research capabilities, circuit settings will not be a problem.

If everything goes well, the prototype will be ready for inspection next year.

In this way, they have lived up to the heavy investment from the machinery factory and deserved Mr. Yang's respect.

Then the two of them talked about some ideas about the calculator and explained some operating principles to Yang Xiaotao.

In this regard, Yang Xiaotao could only cover his forehead and record it bluntly.

God knows how difficult these math problems are.

He would rather make an eighth-level component than waste so many brain cells.

"I have one more thing to do this time."

Just when Liu Yongqiang was about to take out a pen and paper to demonstrate to Yang Xiaotao, Yang Xiaotao quickly interrupted and said.

Colleague, take out a piece of paper from your backpack.

When the two of them took a look, they immediately understood what they were going to do.

Then there was a burst of excitement.

Because this matter is too simple for the two of them.

Isn't it just to calculate the possible composition of metals?

A piece of cake.

And the rewards are huge.

Because of their help last time, I heard that alloy materials were made, so I gave them a lot of rewards.

If they can do it this time, based on their understanding of Yang Xiaotao, they will definitely be rewarded a lot.

"This is a piece of data I got from the Aviation Academy when I went to Jinling on a business trip."

"It should be similar to the titanium alloy last time, but it has an additional material called rhenium, which should be a main material."

Please help me and see if you can help me figure it out.

"no problem."

Wang Kun immediately assured, "I know about the metal rhenium. When I was studying in university, my teacher studied metals, and the research on rhenium was the main topic."

After hearing this, Yang Xiaotao immediately became interested, "Really? Tell me about it."

Liu Yongqiang on the side took the paper and walked to the next door and started to calculate.

Wang Kun then thought for a moment and said, "We all know that parts made of pure metal have many problems, such as rust, insufficient toughness and easy brittleness, insufficient strength and easy breakage. Problems such as these lead to the emergence of alloys.

This material."

"Rhenium is a very useful metal 'additive'. My teacher said that this metal has good plasticity and can be processed into various structural materials, and it also maintains high hardness, high strength and high temperature resistance.

and other characteristics.”

"Yeah?"

Yang Xiaotao was a little excited. If this was true, then this alloy material would really have to be made.

Then I thought that this thing was taken from a burned-out helicopter, and it was from the United States. I can be sure that this rhenium alloy is definitely a good thing.

Wang Kun just scratched his head when he heard Yang Xiaotao's question, "This is what my teacher said."

"Where's your teacher?"

Yang Xiaotao quickly asked whether such a talent would be the most suitable for their machinery factory.

But after Wang Kun heard this, he looked a little depressed, "Teacher, because, because of some problems, I couldn't bear the pressure in my heart, so I chose..."

Yang Xiaotao let out a long breath after hearing this. There are so many such things.

"What a pity!"

Wang Kun nodded, and then returned to the previous topic, "My teacher also said that the future development prospects of this metal rhenium are very good. However, the price is a bit expensive. When he was doing research, there were only 20 people in the entire school.

Gram or so."

"At that time, I used a little but a little less."

"Are there few things like rhenium?"

Yang Xiaotao suddenly realized a problem.

Although China is a vast country with abundant resources, there are also some things that are scarce.

"Few, very few."

Wang Kun said seriously, "My teacher said that most of these rhenium metals are now monopolized by the Alliance and the United States."

"If we want to get these, we have to import them."

"The 20 grams of rhenium in the college were given by the school's professors and tutors when the teachers and others went to study abroad. As for after returning to China, the teachers asked around and never heard that there was a rhenium mine in our country."

"As for metal smelting..."

Wang Kun didn't say much. Yang Xiaotao also understood the domestic smelting situation. Let alone smelting rhenium, even getting tungsten metal out was no small challenge.

"It seems like this rhenium really needs to be thought of."

Yang Xiaotao has not given up research on rhenium alloys.

Since it is useful, it shows that it is necessary to exist.

You can't wait until later for everything.

As for raw materials, Yang Xiaotao suddenly remembered a sentence in "Das Kapital", 'Once there is an appropriate profit, capital will be bold. If there is a 10% profit, it is guaranteed to be used everywhere,... there are 300%

If it wants profits, it dares to commit any crime and even risk being hanged.'
