摘　　要：本文概括总结了传统超高强度钢的强韧化机制,针对2 GPa以上超高强度钢强韧性匹配不足、成本昂贵等突出问题,提出了最小化晶格错配和强有序效应以发展新型超强金属材料,并协同利用高密度共格粒子、高密度位错、弹性畸变中心等多重效应,克服传统共格析出强化合金低塑韧性问题,实现超高强度钢良好强韧性匹配.The term“ultrastrong metallic materials”generally refers to steels and other metallic materials with a yield strength higher than 1500 MPa,along with comprehensively high performance in the properties including toughness,fatigue,stress corrosion,and formability^([1]).Ultrahigh strength steels(UHSSs),a representative class of ultrastrong metallic materials,are typi-cally applied in critical load-bearing components,such as air-craft landing gears,rocket cases and high-performance shafts.
