Optimalizace materiálových vlastností železničních kol

Abstract

This thesis focuses on the optimization of material properties for the production of railway wheels. It deals with issues that affect the resulting mechanical properties. Theoretical part is focused on the technology of manufacture and heat treatment of railway wheels. It describes the production of input material to the measurement wheel laser. Heat treatment of railway wheels is described at the end of theoretical section. The practical part is devoted to the chemical composition of the material and heat treatment regime, the subsequent evaluation of the obtained mechanical values that were achieved due to changes in input material and optimizing treatment regime.
