Russian media praised: Chinese scientists have conquered the world problem and cured the "metal fatigue"!
The service life of high-speed rail wheels is extended by 8 times, and artificial joints are durable for 50 years------
On April 18, Russian media "China Today" published an article.
Chinese scientists have created a unique metal that combines incompatible strength, plasticity, and stability.
Western scientists have been struggling to solve this problem for decades.
The media introduced: researchers at the Institute of Metal Research of the Chinese Academy of Sciences have invented a process that changes the internal structure of metal materials without changing their appearance. As a result, the most ordinary stainless steel can be pumped like liquid, allowing the manufacture of mechanical equipment.
The media explained: metal fatigue is a worldwide problem, which is the process of gradually accumulating metal damage under variable stress.
Traditional metal alloys can break under sudden external forces and will also fatigue and collapse.
Chinese scientists have found a way to overcome metal fatigue. The Institute of Metals has breakthroughly developed gradient nanostructured metals, reducing crack propagation speed by 70% and increasing fatigue life by more than 10 times.
Imagine this: the service life of high-speed rail wheels is extended by 8 times; artificial joints last for 50 years; the inspection cycle of aircraft landing gear is extended from 3 months to 2 years; ball bearings are replaced every 2 months instead of being replaced after years.
Russian experts exclaimed: Chinese scientists always amaze us!
