Cao Weidong picked up a curved metal wire, stretched it at will, and pulled it into a straight line.盍
Then place the metal wire in the sun.
After a while, the metal wire bent automatically and returned to its original shape.
"Does it really have a shape memory function?"
Cao Weidong had a great time.
He had heard the name of memory alloy in his previous life. In addition to having strength and toughness that far exceeded ordinary metal materials, this thing also had an amazing ability.
Shape memory function!
No matter how the memory alloy is bent or deformed.
When it is heated to a certain temperature, the memory alloy can return to its original shape.
Of course, although memory alloy sounds high-end, in fact, it has many successful practical examples.
The more high-end ones are the antennas of the spacecraft.
Due to the limited load capacity of the spacecraft, people made memory alloys into angels, and then compressed the huge spacecraft antenna into a ball on the ground. After taking it into space, it was released to bask in the sun. When the temperature rose to a certain level, the antenna could be
Restore the status quo ante.
As for practical examples of grounding, there are many.
Such as fire alarm systems and water temperature control systems.
Another example is "memory" frames, bone plates, orthodontic wire... 盍
And the famous vasodilator stent that has been used by countless people!
Cao Weidong once read a piece of information saying that memory alloys had actually been discovered a long time ago.
It is said that Yingjiang observed the "memory" function of memory alloy many times in the 1950s.
But they never paid attention.
It was not until more than ten years later when special research on a specific alloy was conducted that the function of memory alloys was taken seriously and practical research was conducted.
Therefore, Cao Weidong is the best in the world in studying the practical application technology of memory alloys in this era.
"This thing has a lot of potential that can be tapped. For example, it can be used to make an early warning valve for a biogas generator, which will automatically lock when the temperature is too high to avoid further disasters."
"Used or used in machine tools..."
Cao Weidong has many application scenarios in mind.
Putting the memory alloy down, he looked at the pile of pure gold ingots in the open space.
All in all, the smelting recipes for four high-precision metal materials have been recorded in the metallurgical blast furnace in the mechanical space. So the focus of the next work is how to put these new materials into practical applications.
】
After all, no matter how precious these new metal materials are, they only have value when they are actually put into production.
But this is not an easy thing.
On the contrary, this is still a long, boring and expensive process.盍
Fortunately, he has mechanical space.
Cao Weidong checked the system virtual screen again.
After this period of harvest, his reserve of shopping points once again exceeded the 10,000 point mark, and is approaching the 20,000 point mark.
No more hesitation.
Cao Weidong directly invested in these shopping points, raising the mechanical space to lv4 in one fell swoop.
After being upgraded to three levels in a row, the mechanical space has also undergone tremendous changes. A vast research laboratory has risen from the ground and appeared in front of Cao Weidong.
[Ding, this upgrade has been completed, the current level of the mechanical space is lv4.]盍
[Your mechanical space opens new functions: 1. New materials research and development laboratory (primary); 2. Blast furnace smelting efficiency improvement.]
"New materials research and development laboratory, this is what I need."
Cao Weidong couldn't wait to check out the functions of the new materials research and development laboratory.
[New Materials R&D Laboratory (Elementary)]
[Function 1: Can carry out research and development of new metal materials and transformation of results]
[Function 2: Preliminary development of special performance materials (high strength, high elasticity, high toughness, high heat-resistant alloys, etc.)]
Cao Weidong's eyes lit up.盍
......
In the days that followed, Cao Weidong was like a hard-working little bee, constantly picking out slag containing rare metals from the warehouse and putting it into the metallurgical blast furnace in the mechanical space.
Pure metal ingots or alloy ingots are produced one by one, and then sent to the new materials research and development laboratory for practical research.
This process lasted for about ten days.
Finally, several research reports were released one after another.
Cao Weidong couldn't wait to read through it and was very satisfied with these research reports.
The research report records many valuable and practical formulas.盍
For example, some kind of ultra-high-strength alloy steel.
By adding different proportions of rare metals such as vanadium, titanium, and nickel to steel, the wear resistance, strength, hardness, ductility and other properties of the steel can be improved, thereby producing higher strength alloy steel.
This high-strength alloy steel can be used to produce key parts. The metal material itself has properties such as wear resistance and high temperature resistance, which can improve the overall performance of the biogas generator.
Cao Weidong made this alloy steel into a baseball bat, and then found an iron-cast knife to test its strength.
Collide the two hard against each other.
A gap immediately appeared on the cast iron tool.
But the baseball bat was intact.盍
Of course, the research report not only records this metal formula, but also various practical formulas for memory alloys, as well as formulas for manufacturing titanium alloys, etc.
In addition, there are valve formulas made of memory metal, metal panel formulas made of titanium alloy, etc.
There are all kinds of cutting-edge materials, about ten or so.
"A priceless treasure..."
Cao Weidong muttered to himself.
To put it bluntly, this research report is priceless.
Even if he asks for the annual sales of a large factory with a thousand employees, the country will agree without hesitation.盍
Of course, the mechanical space has an extremely precise environment and high-precision equipment, which can perfectly restore the performance of metal.
If placed in reality, due to the rudimentary smelting equipment and the more or less doped impurities when purifying rare metals, the smelted special metals will definitely not reach their theoretical best performance.
But when used to produce biogas generators, it can definitely be considered an overuse of materials.
He can guarantee that he is absolutely the only company in the world that can use such good materials to produce biogas generators.
At that time, he had a ten-year warranty in Haikou.
Now it seems that, let alone ten years, as long as there is no man-made damage, maybe these machines can be used for twenty or thirty years.
The research on "slag" in steel plants has officially come to an end.盍
Cao Weidong doesn't plan to stay here anymore.
He copied a copy of the rare metal smelting recipe recorded in the smelting blast furnace, and then packed some metal ingots in a bag, planning to return to the factory to arrange for material updates and iterations.
But just when he came out of the portable space, he suddenly heard the voices of several strange men talking.
There are vague words like "kill him" and "die" mixed in.
Cao Weidong was shocked.
Look up.
I just happened to see a few burly men through the window of the concierge
They seemed to be holding steel machetes in their hands and were gathering outside the concierge.
One of them has even pushed open a crack in the door!
