摘要：
The properties of steels are very dependent on the phases present in the microstructure. The wear resistance and thermal stability of tool steels are achieved with the presence of different types of carbides. So the chemical composition and heat treatment play crucial roles in optimizing the properties of tool steels. The phase transformations in Cr-V tool steel were analyzed during the heating from room temperature up to 1100 degrees C using DTA and dilatometry. After soft annealing the microstructure of the investigated steel consists of a ferritic matrix and M7C3 and MC carbides, as determined with SEM, EDX and XRD techniques. The experimental results were compared to the computational results (Thermo-Calc).
