采用ＳＥＭ、ＴＥＭ 等研究了８６ＣｒＭｏＶ７ 钢锻热淬火后回火过程的组织与性能。结果表明：锻热淬火能提高马氏体的回火稳定性，使粒状珠光体中碳化物尺寸减小，分布更加均匀，显著提高综合力学性能
The microstructure and mechanical properties of 86CrMoV7 steel during tempering were studied by SEM, TEM and so on. The results show that forging quenching can improve the tempering stability of martensite, decrease the size and distribution of carbides in granular pearlite, and improve the comprehensive mechanical properties remarkably
