Optimization of heat treatement process for alloyed case hardenening steel

This bachelor’s thesis deals with the assessment of the influence of heat treatment on the microstructure and mechanical properties of medium alloyed steel 18CrNiMo7-6. The work contains assessment and further proposal of suitable austenitizing temperature for heat treatment. To select the optimal variants of heat treatment five different temperature modes were tested. The theoretical part describes the various methods of heat treatment, with a focus on medium alloyed steels. The practical part presents microstructure of the evaluated steel, its hardenability and hardness depending on the temperature regime of treatment
