\'super steel\' with high strength, ductility developed

by:Newland     2019-09-10
In a breakthrough, scientists have developed a steel with high strength and extensibility, which may have a wide range of industrial applications.
The material cost of steel is only one-
The researchers say this is the fifth type currently used in aerospace and defense applications.
The steel belongs to the medium manganese steel group containing manganese 10 points and 0 points.
Carbon 47%, aluminum 2%, 0.
The price of vanadium, they say, is seven cents.

Strength and extensibility
When the solid material is stretched under pressure --
Metal Material for width-
Scope of application.
However, the researchers say that an increase in strength often results in a decrease in scalability.
In order to solve this problem, the team led by Huang Mingxin of the University of Hong Kong used a new manufacturing technology called deformation and zoning (D&P).
In a study published in the journal Science, the researchers pointed out that when the yield strength of metal materials is more than twice, it is difficult to further improve its extensibility (GPa)
Xinhua News Agency reported.
They made a \"successful attempt to realize their dreams\" because the newly developed method produced \"breakthrough Steel\" with an \"unprecedented\" yield strength of 2.
2 GPa, uniform elongation of 16%.
\"D & P Steel exhibits the best combination of yield strength and uniform elongation in all existing high strength steel
Researchers, including researchers from Beijing University of Science and Technology, said.
The uniform elongation of new steel is much higher than that of metal materials with yield strength exceeding 2.
They said the GPa was 0.
