  • Effect of various heat treatment regimes on structure and properties of Cr-V ledeburitic steel
    Krum, Stanislav ; Sobotová, Jana ; Jurči, Peter
    The tool steels are very specific materials. Generally they have to be hard and wear resistant. This work investigates the influence of sub-zero treatment on mechanical properties and microstructure ... of a PM tool steel. Samples made from the Vanadis 6 ledeburitic type tool steel were heat treated and some of them consequently sub-zero processed. Microstructure of samples was evaluated using optical microscope and scanning electron microscope. Sensitivity against the crack initiation was determined by the three point bending test and hardness was evaluated using Vickers and Rockwell methods. Also a fractographical analysis has been carried out on the three point bending test and hardness was evaluated using Vickers and Rockwell methods. Also a fractographical analysis has been carried out on the three point bending samples
