Description
Summary:This research varies the parameters of austenitization and quenching of the tool steel X155CrVMo12-1. It also focuses on investigation of the structure, hardness and impact energy. It was determined that the cracks were generally intercrystalline, with carbide deposition. It was observed that quenching at the temperature interval from ≈ 700 °C to ≈ 600 °C, at a speed greater than 15 °C/s, achieved higher impact energy with about the same hardness. It was concluded that prevention of carbide coalescence had influence on the reduction of steel fragility.
