Master descends to earth

Chapter 92 High Technology VS Black Technology
Everyone stood in front of the machine and watched the pressure increase continuously. From one to ten, an ordinary saber on the market must reach at least six levels of hardness to be considered qualified. After all, the Rockwell test is the simplest of the four challenges.

Three... Four... Five... Six...

The pressure quickly increased to six, Huangfu Jiang secretly heaved a sigh of relief, and was not very optimistic about Dragon Thorn, thinking that Su Yuan was just playing for tickets.But it would be too embarrassing if it didn't even reach the passing mark.

seven...eight...

"Huh?" Tom's face gradually became serious as the pressure continued to increase. As the technical director of a top brand, he comes into contact with countless steel materials every day.

Dragon thorns are obviously much lighter, probably because the density is not enough, even if it is hand-crafted, it has to go through hundreds of tempering and quenching processes, usually handmade sabers are heavier than industrial flowing water knives.

eight...nine...

The pressure continued to increase, Tom walked to the monitoring platform in a few steps, stared at the constantly flashing data, frowned and did not speak.

The tester looked at the data and asked in a low voice: "Perfect pressure, not exceeding the standard at all, do you want to activate level ten?"

A flash of surprise flashed in Tom's eyes, he turned his head and saw Su Yuan's calm expression, nodded and said: "Activate!"

The tester presses the red button, and the indicator gauge is instantly full, reaching the tenth level of pressure, 280 kg.

It doesn't sound too high, but the unit area of ​​the extremely sharp diamond is less than 0.1 square centimeters, just like an elephant standing on the tip of a needle, the pressure can be imagined.

"Perfect pressure!"

After 15 seconds, the tester finally reported the result, the machine stopped, and the data collection was successful. Tom looked at the graphical analysis table and said excitedly: "It's incredible that it can withstand the pressure perfectly!"

Huangfu Jiang was also surprised, and looking at the calm and composed Su Yuan, he suddenly felt unfathomable. Could this be the number one level in the heaven list?
Tom took the dragon thorn back first, studied it carefully for a long time again, but still didn't see anything special, came to Su Yuan, and said sincerely: "Mr. Su, I apologize for the rudeness just now. This saber is indeed extraordinary. How about continuing to take the test?"

Su Yuan nodded and came here just to show off. Tom excitedly came to the test bench next to him and handed the dragon thorn to the tester with his own hands to start the wear-resistant challenge.

Immersed in the scene, Su Yuan also gradually felt the charm of the saber: the hardness of cutting iron like mud, the tenacity of tenacity, the durability of never wearing out and the perfect rust resistance, just like Wolverine in X-MEN The ultimate goal is to be as strong as the Adamantium alloy in the body.

The wear test is very complicated, and it depends on the manual operation of the tester. It is mainly divided into two parts, namely the static retention test and the dynamic edge impact resistance test. It aims to reflect the comprehensive performance of the tool hardness, retention, toughness and other aspects.

The static retention test is mainly based on cutting and cutting. The cutting edge is 4-5cm away from the root cleaning area as the cutting A area, and three materials that have a significant impact on the blade retention decline: hemp rope, cardboard and dry wood are selected as the cutting objects. , cutting three materials of the same magnitude until the retentivity decays.

For the dynamic edge impact test, the test edge area selects the 4-5CM area of ​​the first half of the blade as the B area, which is separated from the retention test area to ensure the relative fairness of the test.

By impacting the cutting edge on materials with different hardnesses, the impact resistance of each steel material's cutting edge is examined to determine whether it is easy to curl or chip.The materials are mainly divided into four types of materials with progressive hardness: harder thick dry wood, 6061 aluminum rod, H59 brass rod, and 304 stainless steel.

All the testing process was monitored and videotaped to ensure fairness and justice. The tester started under Tom's signal. The A-zone retention test consisted of 20 meters of hemp rope with a diameter of 15MM, 20 pieces of cardboard with a diameter of 100CMX60CM, and outdoor dry wood with a diameter of 2-4CM.

B区抗冲击测试，硬干木7.5CM直径，6061铝棒 10mmX1米，H59黄铜棒5mmX，304不锈钢棒 5mmX半米。

Finally, the score ratio is calculated according to the persistent decline. Once the subjective white line or objective A4 paper decline occurs, the total score is calculated.

The tester held the dragon thorn and started the test meticulously, moving quickly without any hesitation or pause. 1 minute... 3 minutes... 5 minutes... 10 minutes...

The more Tom looked, the more surprised he became. You must know that the seemingly ordinary hemp rope and cardboard are a huge test for sabers. Quantitative changes lead to qualitative changes. Once the quantity exceeds the limit, the sharpness will immediately decline, which will seriously affect the efficiency of use.

But this dragon thorn...

To say that the coolest thing is the tester, I have never felt so relaxed and smooth, so cool that I don’t want to stop at all!

I don't know how long it took, but suddenly found that all the test materials were swept away, raised his head in a daze, licked his lips, and asked, "Do you still need to continue?"

Tom took a deep breath and knew the result without calculation, ten, full marks!
The data was collected again and appeared on the big screen. The Rockwell hardness was ten points and the wear resistance test was ten points. Dragon Thorn instantly surpassed countless competitors and jumped in front of everyone.

"Huh? Look at the big screen!"

"dragon of bayonet? Both are full marks?"

"MY GOD! I read it right!"

Su Yuan saw that many people in the hall began to discuss and smiled, this is the effect required by the system. What platform is more suitable for becoming famous overseas than here?

Tom picked up the dragon thorn and excitedly went straight to the third test point, the bending vibration exercise, which is also one of the most difficult of the four challenges.

The so-called bending vibration is to use ultrasonic waves of different frequencies to conduct a comprehensive test on the blade. The intensity ranges from one to ten, and more than seven is considered a high-quality product.

It is the biggest test of the toughness of steel. Once the computer monitors the blade to produce a bending deformation of more than three degrees, it is considered unqualified, the challenge fails, and the data collection is confirmed.

Because of the short length of the saber, more than three degrees of deformation or inclination will seriously affect the efficiency of use. For several top brands, bending vibration and corrosion are battlegrounds for military strategists, and they best represent the embodiment of technological content.
