结果表明:回火索氏体是最佳的组织形态;微观硬度的不均匀性显著影响钢的表面加工质量。
The results indicated that the tempered sorbite was the optimum microstructure, the inhomogeneous distribution of micro hardness affected markedly the finish quality of the steel surface.
完全硬化区由细小针状马氏体、残余奥氏体和少量点状碳化物组成,过渡区由马氏体和回火索氏体(珠光体)组成;
The completely hardening region is composed of fine acicular martensites, residual austenites and a few dot-like carbonides and the transition region is made up of martensites and sorbites (pearlite).
