Best Model! New Materials
After eating with Ye Zhou in the cafeteria.
Cheng Hao returned to the dormitory.
Looking at the mathematical model in front of him, Cheng Hao began to find the optimal solution of the mathematical model in front of him according to the pattern.
This process is not that difficult. In terms of Cheng Hao’s own mathematical skills, this process is not even as difficult as sorting out the data and mathematical models by himself last night.
But after all, there are too many data. If Cheng Hao wants to get something, he must observe the entire mathematical model in front of him.
The pen in Cheng Hao’s hand kept moving.
Calculating the optimal solution of the model in front of him.
In the end, at eleven o’clock in the evening, Cheng Hao still hadn’t calculated the optimal solution.
“What went wrong??”
Cheng Hao frowned and looked at the draft paper in front of him. It was densely filled with formulas, but the optimal solution obtained on it conflicted with the mathematical model he created!
Scratching his hair, Cheng Hao was a little bit crazy. He was very confident in his mathematical calculation ability, but the current mathematical model somewhat violated this aspect.
Is it really so difficult to calculate the direction of materials?
To be honest, in fact, the direction of computational materials science is more inclined to major in chemistry, but chemistry and physics sometimes overlap, especially in the field of materials.
After calming down for a while, Cheng Hao continued to look at the mathematical model in front of him.
At this moment, the little u next to the computer screen suddenly sent a message.
“Master, what is this bump on this mathematical model?”
Seeing Xiao u’s words, Cheng Hao smiled.
He typed a string of characters casually.
“This was during the experiment. Some impurities were mixed in due to improper operation, which caused the mathematical model to be unsmooth.”
“Will these impurities affect the final value of the material?”
Xiao u, the artificial intelligence, has been trained by Cheng Hao for a long time, and his learning ability has begun to improve.
“Generally not, unless it is a large-scale impurity doping, such a small amount of impurity doping will not affect the value of the final material.”
Cheng Hao casually said to Xiao u.
After finishing speaking, Cheng Hao suddenly felt as if struck by lightning, and his eyes suddenly lit up.
correct! Large scale impurity doping.
For the problem of the mathematical model in front of us, why not try impurity doping?
Thinking of this, Cheng Hao did what he said and started to simulate the mathematical model on matlab. According to the previous data, Cheng Hao directly carried out a large number of simulations.
A large number of other materials were selected for simulation on the model.
Then perform numerical calculations!
Soon, Cheng Hao found the optimal solution!
The polyvinyl alcohol (PVA) composite material with a graphene content of 1.9vol% is coated on the titanium alloy material, and its mechanical properties are displayed according to the data on the mathematical model. It is found that the tensile strength of the composite material is higher than that of the pure titanium alloy material. Increased by 150%, Young’s modulus increased by about 5 times!
More importantly, other aspects have been improved to varying degrees!
And this polyvinyl alcohol (PVA) composite material with a graphene content of 1.9vol% is more like a paint!
The foundation of the titanium alloy material itself is strong, and after adding this paint, it is even stronger!
“Yes!”
Cheng Hao’s eyes showed excitement, he finally found it!
After heaved a sigh of relief, Cheng Hao felt dizzy in his head, and fell asleep on the bed.
The next day, the first thing Cheng Hao did when he woke up was to come to the laboratory with a USB flash drive.
“Professor! I’ve got it done!”
Cheng Hao excitedly turned towards Academician LinSaid.
Academician Lin was stunned for a moment, and Zhou Ming and Zheng Sen looked at each other immediately, with a look of hesitation in everyone’s eyes.
“Data, have you finished processing?”
Academician Lin hesitated for a moment, and asked Cheng Hao who was in front of him.
“right!”
With that said, Cheng Hao directly inserted the USB flash drive into the computer beside him.
The people nearby quickly gathered around, opened Matlab, and swiped, a huge mathematical model appeared in front of everyone.
“Damn it! The math model made by the elementary school brother is really beautiful!”
Zhou Ming looked at the mathematical model in front of him with some surprise.
The eyes of Zheng Sen and Zhang Ming on the side were also shocked.
At this time, Cheng Hao continued to click on the model to display the calculation results.
Academician Lin looked at the mathematical model in front of him with a serious expression. He could tell that the mathematical model in front of him was not just beautiful!
What I did was really good. Soon, the data kept stacking and changing, and finally an optimal solution appeared.
“Polyvinyl alcohol (PVA) composite material with a graphene content of 1.9vol% is coated on a titanium alloy material?”
Looking at the optimal solution in front of him, Zhou Ming showed a trace of doubt in his eyes. He looked at Cheng Hao in front of him and said, “Is there something wrong with your mathematical model?”
“Yes! Primary school brother, we have also done similar experiments. Graphene and other materials were used to coat titanium alloys. If I remember correctly, we have also done polyvinyl alcohol, but the amount may be wrong. I remember When doing it, the coating in this situation has no advantage at all!”
Zhang Ming frowned. He adjusted his glasses and said to Cheng Hao who was in front of him with a little hesitation.
“First of all, in your experiment, there must be some “impurities” missing, and then the process of ionization is missing!”
Cheng Hao smiled slightly, and said to the three people in front of him.
“Impurities?”
“Yes! Among these pva materials, I added a little bit of pvc material to the mathematical model!”
Cheng Hao smiled slightly, and said to the three people in the laboratory with a smile.
At this moment, Zheng Sen on the side wanted to say something else.
“Zhou Ming, go and reset the experiment, try it!”
Academician Lin on the side has already spoken.
“okay!”
Soon, everyone began to reset the experiment according to the data on the computer.
According to the experimental process of computer data.
The graphene is separated, doped into the pva solution, and then slightly doped with some pvc materials. After fully dissolving, it is then put into the titanium alloy, and finally ionized.
Finally, the titanium alloy was taken out.
The titanium alloy in front of it has changed a little bit, a faint blue light appeared on it, and everyone around looked at the titanium alloy in front of them curiously.
Then conduct experiments on the mechanical level.
Experimental results: Compared with pure titanium alloy materials, the tensile strength has increased by 130%, and the Young’s modulus has increased by about 3 times.
Looking at the experimental results in front of them, the eyes of the three Zheng Sen around them all revealed expressions of disbelief.
It’s just an improvement of the layer, why can the material itself change so much? ? ?
Strength increased by 130%!
You know, this is titanium alloy! And this is only the first experiment, and it can be optimized by changing the process in the future!
