The more one thought they understood something or technology, the easier it was for them to think that they were seeing something wrong when they saw something they couldn't understand.
Kobayashi Well and his team thought that Japan University of Technology's research on powder metallurgy was far better than Zhongyun University's.
However, when they saw Ye Qing's mixing technique, they felt that it was very funny.
High-purity alcohol had volatile characteristics. In theory, it could be used as a humidifier. However, when it was used in various metal and non-metal powders, there might be a chemical reaction. Also, because the embryo was compressed by the hydraulic press, the powder density increased, and the alcohol inside could not completely evaporate.
In order to solve this problem, the embryo had to be naturally shelved for a long time to allow the alcohol to completely evaporate.
First, it was a waste of time. Second, after the embryo was dried, there might be slight deformation, which increased the failure rate of the product.
This kind of technology had long been eliminated at Zhongyun University, and they changed it to a special humidifier.
There was also the mixing. This laboratory only had a backward ball mill, and now the three-dimensional motion mixer was the standard equipment in a first-class laboratory.
There were too many flaws, and he couldn't complain!
Kobayashi Well felt like he had returned to 30 years ago, when he visited a university laboratory.
Ye Qing turned a deaf ear to the sneers and mocking gazes of the Japan University of Technology. He minded his own business and mixed the five main powders. Then, he put them into the ring molds of different specifications and used a hydraulic press to cast them into five circles of different sizes.
The smallest circle was only the size of a wine bottle cap, and the largest was the size of a bracelet.
If one measured their diameter, one would find that the rings were small to large, and the outside of each ring was slightly larger than the one on top.
"Making the five rings of the Olympics?" Tanaka laughed very unkindly. "The 2020 Olympics will be held in our country. Speaking of which, our school is responsible for the design of the mechanical automation system in the [New National Arena], where the opening ceremony will be held."
Ye Qing adjusted the focal length of an industrial microscope used to observe the micropore structure on the surface of the material. Then, with the help of the microscope, Ye Qing used a micrometer to carefully measure the size of each round embryo. At the same time, he used a carving knife to carefully carve the semi-arc concave and convex surface on the edge of each embryo.
After finishing the engraving, Ye Qing put the five rings together and recast them with a hydraulic press.
The semi-arc-shaped concave and convex surfaces were magically fused together after the hydraulic press applied 500 tons of pressure.
Without giving them time to appreciate it, Ye Qing sent the finished product directly into the vacuum sintering furnace that had been preheated.
No one from Zhongyun University spoke. They were all nervously watching the temperature of the sintering furnace rise little by little.
Ye Qing looked at the watch on his left hand and said calmly, "Wait for another twelve minutes."
"Do you want me to count the time for you?" Kobayashi Well raised his left hand as if he was showing off. He showed off a silver-white dial with a matte black metal band and shook it. "Seiko Sanwen mechanical watch with a chronograph function. The error of the daily travel time is controlled within 0.5 seconds."
"Uh …"
Ye Qing pulled his sleeves to cover the Patek Philippe 2499 red gold series in his hand. There were only a few Patek Philippe 2499 red gold series watches in the world. He said with some difficulty, "No … need."
The somewhat antagonistic atmosphere lasted until the protective nitrogen gas was re-injected into the vacuum electric arc furnace to balance the internal and external atmospheric pressure. Only then was it broken by the huge tension.
"It will definitely shatter like glass," Kobayashi Well whispered in Tanaka's ear. He was not worried that they would be turned around.
Ye Qing smiled. He put on a pair of thermal gloves and used a pair of special pliers to pick up a piece of flaming red disc that looked like a piece of jade.
The flaming red disc was like a magnet, instantly attracting everyone's attention.
In the powder metallurgy laboratory, there was a series of gasps.
"It actually didn't shatter?" Professor Kobayashi Well rubbed his eyes in surprise.
When an object was heating up, due to the heat transfer of the material, if there was a crack on the object, it would become a very obvious black crack. However, the flaming red disc in front of them was a complete whole.
The flaming red disc was losing its heat bit by bit.
A touch of emerald green was the first to appear at the outermost periphery of the disc. Under the surrounding hot halo, the outermost emerald green became exceptionally transparent, flickering with a sparkling luster like jade.
Then, the second flaming red faded, and the silvery white metal outline made Kobayashi Well's eyeballs expand as if they were inflated.
Then, the third purple, the fourth white, the fifth transparent …
Green, silver, purple, white, transparent. Five different colors were combined together. They intertwined with each other, forming a natural combination.
Silver and white were metallic materials, while the other three were non-metallic materials.
Sintering between different metals was already a high-end technology that was difficult for a lot of people. However, Ye Qing was now holding five different colors and different types of sintering.
The laboratory lights just happened to give it a layer of hazy and dense five-colored luster. As the last bit of red faded, this exquisite disc seemed to come to life, and there was life flowing inside.
"Impossible!" Tanaka, who had just demonstrated the sintering of two metals in the afternoon, jumped up. Not only did he stop breathing, but even his thoughts were already stopped.
There were no gaps, and it was a natural combination.
"The difference in melting point between zinc metal and quartz is a full 1150 degrees. If you want to sintering quartz into a transparent color, zinc metal with a melting point of only 420 degrees would have already melted into a pile of waste."
"This doesn't conform to science."
"You're talking about pure zinc, but don't you know that the most common way to use zinc is to mix it with other metals and become an alloy?"
"I don't believe it, then tell me. Even if it's a zinc alloy, how can it be perfectly combined with quartz? "
There was no why. When the five-colored disc cooled down, Ye Qing directly handed it to the Japan University of Technology.
Unwilling to give up, they placed the five-colored disc under an industrial microscope and looked at it with the most critical eyes, but they still couldn't find any cracks in it.
On the other hand, the Zhongyun University students were immersed in the joy of tasting the immortal peach trees.
The Japan University of Technology students wished they could drill into the five-colored disc and see the mysteries of the atomic structure inside. Their expressions made them happy from the soles of their feet to the top of their heads.
Was the competition still going on?
Sintering five materials was much more difficult than sintering two materials.
This didn't include the difficulty between metals and non-metals. They were completely at different altitudes. Even the Himalayas couldn't bridge the gap between them.
"Have you seen enough?" Yun Tianjie, a freshman, walked in front of Tanaka with the attitude of a victor.
