【 摘 要 】

Results of the study of the change in the microstructure of St3 steel using different methods of heat treatment are presented. Comparison of hardness during bulk quenching and quenching by a highly concentrated heat source (plasma arc) is given. Description of the obtained microstructures is presented.
