Supervisor: prof. Ing. Peter Jurči, PhD.

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

Project description:The main goal of the project is to determine the optimal temperature and duration of sub-zero treatment with particular interest to get the best complex of microstructure and important properties of Cr-V ledeburitic steels. The second object of the interest is to determine a "window of properties improvement" e.g. the combination of sub-zero treatment and tempering temperatures where simultaneous improvement in strength and toughness can be achieved. A commercially available PM Cr-V ledeburitic tool steel will be used as experimental material. The effects of heat treatment variables such as the temperature and the duration of sub-zero treatment and tempering regimes, at constant regimes of the austenitizing and quenching, on such important characteristics like the microstructure, hardness, toughness, fracture toughness and wear resistance will be investigated. In the project, variety of investigation techniques will be utilized complementarily, which makes it possible to achieve the main goal of the project.
