The more you think you know something or technology, the more likely you are to think that you are seeing something wrong when you see something you can't understand. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Kobayashii and his entourage think that the Japanese University of Science and Technology far surpasses Zhongyun University in the research of powder metallurgy technology.

Then after seeing Ye Qing's blending technique like a pigment, I felt very funny.

High-purity alcohol has volatile properties and can theoretically act as a humidifier. However, when used in various metal and non-metal powders, there may be chemical reactions, and the density of the powder will increase due to the compression of the embryo by the hydraulic press, and the internal alcohol will not be completely volatilized.

To solve this problem, it is necessary to place the embryo naturally for a long time to allow the alcohol to completely evaporate.

This is a waste of time, and the embryo may be slightly deformed after drying, which will increase the failure rate of the product.

This technology has long been phased out on their side and replaced with specialized humidifiers.

There is also mixing, there is only a backward ball mill in this laboratory, and now the three-dimensional motion mixer is the standard instrument in the first-class laboratory.

There are too many bad points, and I can't complain about it!

Kobayashi had the feeling of being backward when he went back to 30 years ago and visited the university laboratory.

Ye Qing turned a deaf ear to the sneering and mocking gaze of the Japanese University of Science and Technology, and mixed the five main powders by himself, and then put them into ring molds of different specifications, and used a hydraulic press to die-cast them into five circles of different sizes.

The smallest round fitting, the size of a wine bottle cap, and the largest is about the size of a bracelet.

If you measure their diameter, you will find that the rings are small to large, and each ring is slightly larger than the one above.

"Do you want to make the Olympic rings?" Tanaka smiled very unkindly: "The 2020 Olympic Games will be held in our country, and the [New National Stadium], where the opening ceremony will be built, will be designed by our school. ”

An industrial microscope used to observe the microporous structure of the surface of the material was adjusted by Ye Qing, and then with the help of a microscope, Ye Qing carefully measured the size of each round embryo with a micrometer, and at the same time used a carving knife to carefully carve a semi-arc-shaped concave and convex surface similar to a gear on the edge of each embryo.

After all the engraving, Ye Qing accurately combined the five ring sleeves together and recast them with a hydraulic press.

Those semi-arc-shaped concave and convex surfaces, after being cast by a hydraulic press with a pressure of 500 tons, were magically fused together.

Without giving them time to appreciate, the embryos were assembled and directly sent by Ye Qing into the preheated vacuum sintering furnace.

No one from Zhongyun University spoke, and they were all nervously watching the temperature of the sintering furnace rise little by little.

Ye Qing looked at the watch in his left hand and said calmly: "Wait for another twelve minutes." ”

"Do you want me to help you count the time?" Kobayashi Jing showed off, raised his left hand, showed a silver-white dial, matte black metal strap watch, and shook it: "Seiko minute repeater mechanical watch, with chronograph function, the daytime error is controlled within 0.5 seconds." ”

"Uh......"

Ye Qing tugged at his sleeve to cover the piece on his hand, there are only a few pieces of Patek Philippe 2499 red gold series in the world, and said with some difficulty: "No...... I used it. ”

Some of the opposing atmospheres were not broken until the vacuum electric arc furnace was re-injected with protective nitrogen to balance the internal and external atmospheric pressures.

"It's definitely going to shatter like glass. Kobayashi muttered in Tanaka's ear, not at all worried that their side would be overturned.

Ye Qing smiled, wearing heat-insulating gloves, and using special pliers, he took out a piece of disc that was burning red and looked a little like jade.

The fiery red disc was like a magnet, instantly attracting everyone's attention.

In the powder metallurgy laboratory, there was a sound of inhalation.

"It's not broken?" Professor Kobayashi rubbed his eyes, looking surprised.

When an object is heated, if there is a crack in the object due to the heat transfer of the material, it will become a very obvious black gap. But the fiery red disc in front of me is completely a whole.

The fiery red disc is fading away little by little.

A touch of emerald green first appeared on the outermost part of the disk. Under the scorching halo around it, the outermost emerald green became extremely transparent, shimmering like a crystal luster like jade.

Then the second fiery red faded, and the silver-white metal outline made Kobayashii's eyeballs inflatable and bigger as they stared.

Then there is a third purple, then a fourth white, and a fifth transparent......

Green, silver, purple, white, transparent. Five different colors are combined together, and they are intertwined with each other.

Silver and white are metallic materials, and the other three are non-metallic materials.

The sintering between different metals is already a high-end technology that has stumped a large piece. But what Ye Qing is holding up now is five different colors and different types of sintering.

The laboratory lights just gave it a hazy five-color luster. With the last bit of fiery red fades, this delicate disc seems to come alive, and life flows inside.

"Impossible!" Tanaka, who had only shown two metal sinters in the afternoon, jumped up, not only breathing, but even suffocating his thoughts.

There are no gaps, and it is natural.

"The melting point difference between zinc and quartz is 1150 degrees, and if you want to sinter quartz into a transparent color, the melting point is only 420 degrees, and it has long been melted into a puddle of waste. ”

"It's not science-free. ”

"You're talking about pure zinc, but don't you know that the most common way zinc is used is to mix it with other metals and make alloys?"

"I don't believe it, so tell me. Even if it's a zinc alloy, how can it be perfectly combined with quartz?"

There weren't so many whys, and when the five-color disc cooled down, Ye Qing directly handed it to the Japanese University of Science and Technology.

They rested on the five-color disc under the industrial microscope and looked at it with the most critical eyes, but they still couldn't find any cracks in it.

Zhongyun University, on the other hand, fell into the joy of tasting the fairy fruit of the peach orchard.

The hatred of the Japanese University of Science and Technology here is that they can't get into the five-color disc and get a glimpse of the mystery of the atomic structure inside, which makes them cool from the soles of their feet all the way to the Tianling Gai.

Compared to the bottom of the none?

How many times is the sintering of five materials higher than the sintering of two materials?

This is not counting the difficulty between metals and non-metals, which are not at the same altitude at all, and the Himalayas cannot catch up with the gap between the moats.

"Have you seen enough? Yun Tianjie, a freshman, walked in front of Tanaka's classmates as a winner.

"Hey~ loser, you should fulfill your promise and apologize to us. (To be continued.) )
