摘要
用透射电子显微分析方法研究了一种Cr-Co-Mo超高强度不锈齿轮(轴承)钢中的强化相,结果证明,钢回火时与M体共格沉淀析出一种密排六方结构Laves(Fe2Mo型)强化相,并和M2C碳化物一起成为二次硬化的原因。
The strengthening phases in a ultrahigh strength stainless gear(bearing) steel have been investigated by TEM electronic micrographs and diffraction techniques.The results show that two types of hcp phases:Laves(Fe2Mo type) and M2C have been precipited in coherence with martensitic matrix during tempering and both of them may be ascribed to the existence of secondary hardening phenomenon in the steel.
