Paper Title:
Study on the Structure of Grind-Hardened Layer and Parameter of Hardening Depth of 42CrMo Steel
  Abstract

Grind-hardening test were performed on MM7132 surface grinder with corundum grinder wheel in the mesh of 60#. The result shows that the structure of grind-hardened layer is composed with lath martensite and small mixed martensite; the depths of grind-harden layer is largest when the grind depth is 0.3mm, while the depths of grind-harden layer decreased when the grind depth is 0.2mm, 0.4mm, 0.5mm,respectively. The range of microhardness of grind-harden layer is from 754 to 853. The depths of grind-harden layer along the direction of working appeared ladderly.
