Reduction of Retained Austenite in Tool Steels

Abstract Tools are devices for machining materials which must have different properties depending on their intended application. These determined by the chemical composition and microstructure of tool steel. The desired steel can be achieved with suitable heat treatment technology. During this treatment, may develop various lattice structural transformations in turn cause internal stresses, cracks distortions. One possible reason these undesirable results retained austenite. effects most pronounced steels. In study, possibilities reducing amount residual austenite during is investigated.
