摘　　要：针对超高强度钢存在的高强度低韧性、低应力腐蚀性能等问题,综述了这类钢的性能特点、强韧化探索和制约因素,并提出细化纳米相析出技术、超高强度不锈钢、洁净钢技术、材料计算科学和特种定制材料等是超高强度钢发展的重要方向。In view of the existing ultra high strength steel with high strength and low toughness,low stress corrosion problems,the performance characteristics,strengthening and toughening exploration and constraints of the were summarized. The important development directions of the ultra high strength steel are put forward,such as the refinement of the nano phase precipitate technology,the ultra high strength stainless steel,the clean steel technology,the material computation science and the special custom material.
