The microstructures of three steels with about 0.35% C, 10% Mn and 13% Cr were investigated. After homogenization treatment, all steels have an austenitic microstructure with some carbide precipitates. During cooling to −196°C as well as by plastic deformation ε‐martensite and α‐martensite are formed. The influence of the degree of deformation at different temperatures on microstructure and stability of austenite is described in detail. This information will be used to find a microstructure optimized to have a high cavitation resistance.
