Abstract

This bachelor’s thesis deals with heat treatment of steels. Iron-carbon diagram and basics of heat treatment are described in the beginning of the literature search. Further the thesis focuses on austenitization and changes during decomposition of austenite. Introduction to transformation diagrams and their use is also included in this thesis. At the end the thesis focuses on description of individual heat treating methods. The experimental section contains metallographic analysis of 4 samples made of low carbon steel
