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.
