Abstract
Diploma thesis refers about heat treatment of hot-rolled grinding balls, which are made from hypereutectoid steel. Theoretical part of thesis describes quenching process, residual stresses and hardening. Moreover describes phase transformation products during quenching. In experimental part is carried out analysis of manufacturing process, hardness measurement and consequent evaluation of grinding balls in terms of purity and microstructure.
