This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:The project is focused to thorough investigation of phenomena, which take place in selected chromiumvanadium ledeburitic tool steel when it is sub-zero treated using various temperature-time regimes. The effects of important heat treatment variables such as the austenitizing temperature, tempering regime, temperature and duration of sub-zero treatment on the microstructure, hardness, flexural strength, fracture toughness, wear resistance and corrosion resistance of investigated material will be determined. This would lead to an achievement of an opportunity to fully exploit the potential of sub-zero treatment of tool steels. In the project, variety of experimental techniques will be utilized, which would make it possible to achieve the main goal of the project - to confirm the main scientific hypothesis pertaining the possible simultaneous enhancement of normally “conflicting” material properties like the hardness and wear resistance on the one side and the toughness, on the other side, of selected Cr-V ledeburitic steel, by the use of sub-zero treatment.
