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 the investigation of phenomena taking place in selected chromium-vanadium ledeburitic tool steel when it is sub-zero treated using various regimes of the treatment. The effects of important heat treatment variables such as the austenitizing temperature, tempering regimes and hold at the temperature of sub-zero treatment on the microstructure, the hardness, the three point bending strength, the fracture toughness and the wear resistance will be determined. In the project, variety of investigation techniques are planned to be utilized, which makes it possible to achieve the main goal of the project - to make a serious and comprehensive analysis what happens in the microstructure of selected Cr-V ledeburitic steel when sub-zero treated using various regimes and, what is an impact of microstructural changes on mechanical properties and tribological performance of the material.
