Publikováno v: Journal of Manufacturing and Materials Processing, Vol 2, Iss 1, p 20 (2018)

During the process of grind-hardening, the dissipated heat from the process is utilized for a surface layer hardening of machined components made of steel. A martensitic phase transformation occurs within the affected subsurface regions and compressi
