本文研究了T10A高碳弹簧钢的氢脆敏感性与组织形态的相互关系。研究表明,在机械性能相近条件下,组织形态对高碳弹簧钢的氢脆敏感性影响较大,当钢的基体组织细密和碳化物形态呈圆形细小均匀弥散分布时,氢脆敏感性较小。细化马氏体组织和残留碳化物,增加板条马氏体的相对量,可改善高碳弹簧钢对氢脆敏感性。 In this paper, the relationship between hydrogen embrittlement sensitivity and morphology of T10A high carbon spring steel was studied. The results show that under similar mechanical properties, the morphology of the embrittled steel has a significant effect on the hydrogen embrittlement susceptibility of high-carbon spring steel. When the microstructure of the steel is fine and the shape of carbide is small and uniform, small. Refine the martensite and residual carbides, increasing the relative amount of lath martensite can improve high carbon spring steel sensitivity to hydrogen embrittlement.
