The heat flux generated in grinding is utilized to induce martensitic phase transformation in the surface layers of components, such as that achieved by other surface strengthening processes. It is certified by temperature field analysis and phase transformation research that simulating the grind-hardening temperature field by computer could reduce research time and save experiment cost greatly. On the basis of simulating temperature field, the depth of hardness could be forecast and controlled by selecting various grind-hardening parameters.
