Experimentální a teoretické stanovení teploty likvidu u nástrojových ocelí

Abstract

The thesis is focused on the analysis of lyquidus temperatures. The theoretical part was devoted to the crystallization and solidification of steel, the effect of liquidus temperatures on phase transformations and the possibility of how these temperatures can be determined. The experimental part is devoted to measuring liquidus temperatures using direct thermal analysis for tool steel 51CrV4. Furthermore, calculations in the CompuTherm database and the use of empirical equations to verify and compare the calculated and measured data.
