Nalezení závislosti velikosti austenického zrna na vstupních parametrech

Abstract

The purpose of this thesis is finding dependence of austenitic grain on input parameters. Selected input parameters are chemical elements of steel composition. These selected chemical elements may have a majof effect on the size of austenitic grain. The chemical elements are N, S, Al, Cu and Ti. This thesis contains a brief introduction into the issue of grain stability of case hardening steels and possibble starting points for finding the stability of austenitic grainf. Furthemore, this thesis contains statistical methods udes in this thesis in the practical part.
