中科院金属所纳米晶304不锈钢板材研究取得重要进展

Core Viewpoint - The research conducted by the Institute of Metal Research, Chinese Academy of Sciences, has developed a nanocrystalline 304 stainless steel plate (NCP-304) using deep rolling technology, which shows improved high-temperature oxidation resistance, corrosion resistance, and strain fatigue performance compared to conventional 304 stainless steel (TPC-304) [1] Group 1: Material Properties - The nanocrystalline 304 stainless steel exhibits enhanced mechanical and corrosion resistance properties simultaneously, regardless of the interaction between stress and corrosion [1] - The sensitivity to strain rate is reduced in the nanocrystalline 304 stainless steel, indicating better performance under varying conditions [1] Group 2: Industrial Implications - The findings from this research are expected to facilitate the industrialization of nanocrystalline 304 stainless steel plates, promoting lightweight, long-lasting, and energy-efficient devices and equipment related to 304 stainless steel [1] - The study provides a new perspective on understanding the mechanical and corrosion properties from the viewpoint of material valence electronic structure, potentially leading to more universal theories in material science [1]
