摘要
对普通热冲压成形钢,高淬透性、高抗氧化性热冲压成形钢,高强韧性热冲压成形钢,超高强度热冲压成形钢,高抗氢脆敏感性热冲压成形钢,纳米粒子强化超高强度热冲压成形钢等热冲压成形钢近年来的发展概况进行了综述,分析了热冲压成形钢零件轻量化与功能性的关系,强度与氢脆之间的关系,以及组织细化对其强韧性的影响机理,并对热冲压成形钢今后的发展方向提出了建议。
Development in recent years of hot stamping steels,including ordinary hot stamping steel,hot stamping steel with high hardenability and oxidation resistance,high strength ductile hot stamping steel,ultra high strength hot stamping steel,high hydrogen embrittlement sensitivity hot stamping steel and ultra high strength hot stamping steel reinforced by nanoparticles,is summarized.The relation between lightweight and functionality of hot stamping steel parts,the relation between strength and hydrogen embrittlement and the influence mechanism of microstructure refinement on strength and toughness are analyzed.The suggestions for the further development direction of hot stamping steels are put forward.
