Chinese scientists have achieved results in the research on lightweighting of metal materials

On August 9, 2024, the news reported the achievements of the Institute of Metal Research of the Chinese Academy of Sciences in the research on lightweighting of metal materials. The research team of the institute achieved a reduction in material density and a significant increase in material strength without losing or even improving plasticity by dispersing holes with diameters of less than a hundred nanometers in the material. This achievement has been published online in the international academic journal "Science".

Experimental data shows that the yield strength of the new material after the introduction of nanopores has increased by 50% to 100%, which means it has a higher bearing capacity. This new type of strengthening method not only contributes to the lightweighting and recycling of materials, but also retains the excellent physical properties such as thermal and electrical conductivity of the bulk material to a greater extent. It is expected to be applied in multiple fields such as aerospace in the future.
