日本从97年开始立项进行2个有关金属材料的国家级课题,它不是仅依赖于合金化,而是通过细化金属组织来实现材料的高强度、高韧性、长寿命、高性能。目标是把粒径从现在的10μm突破到1μm。
Since 1997, Japan has started to conduct two state-level projects on metal materials. It does not rely solely on alloying. Instead, it realizes the high strength, toughness, long life and high performance of the material by refining the metal structure. The goal is to break the particle size from the current 10μm to 1μm.
