| Abstract: | 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. |
