利用高碳钢淬火试样及淬火后充氢试样的拉伸试验,研究了高碳钢淬硬组织对氢和应力的敏感性。
The sensibility of the harden structure of high carbon steel to hydrogen and stress is researched through the tensile test of quenched specimens and charging hydrogen specimens after quenching.
结果表明:对于碳含量有差异的钢板,其显微组织、晶粒度及夹杂物等级均属正常,焊缝中未发现淬硬组织;
The obtained results indicate that the microstructure, grain-size and inclusion level of said steel plates were normal, hardened structure induced from quench had not been found;
回火完全淬硬钢得到的最终组织结构被称为回火马氏体。
The final structure obtained from tempering a fully hardened steel is called tempered martensite.
