Abstract

The main goal of this article is to present the results of state the microstructure in chromium ledeburitic tool steel commercially named Sverker 3. This material was treated by austenitizing at various temperatures and then quenched in oil. Paper is focused on distribution and change in carbide particles depending on austenitizing temperature. Analysis was focused on population of these particles and classification particles by EDS analysis results and measuring of hardness. According to chemistry of particles were particle sorted by types. Beside that all results are compared to phase equilibrium calculated in Thermo-Calc.

Keywords: Ledeburitic tool steel, quenching, microstructure, carbide particles
