Research project P1125 (AiF-IGF 19289N): Cryogenic treatment of tool steels to improve technological properties (Nanocarbide)

Cryogenic treatment of tool steels increases toughness and wear resistance. The aim is to change the microstructure by precipitation of nanocarbides throughout the whole cross section (Figure 1). Integrating the cryogenic treatment in the heat treatment chain provides a substantial cost reduction as an alternative to coating and surface layer methods. This project will lead to a basic understanding of the efficiency of cryogenic treatment by investigating submicroscopic processes. These include microstructural investigations by means of scanning and transmission electron microscopy and mechanical tests.
