Abstract

The critical points of three experimental tool steels are determined. The influence of austenitization temperature on martensitic transformation start temperature is investigated. CCT diagrams are determined by measuring physical properties during continuous cooling. Microstructure and hardness of phase components of specimens cooled with different rates are studied
