Abstract

The cyclic properties of coarse-grained cast austenitic manganese (Hadfield) steels were studied. The material cyclically hardens, with a pronounced memory effect which is common to austenitic steels. The cyclic flow curves were different for the wrought and the cast condition of the material; however low cycle fatigue properties are similar for the two conditions. Typical features of monotonic deformation and fracture (ea orange peel and surface coarse slip bands) were also noted on the surface of compact tension specimens used for fatigue crack growth rate measurements. Contrary to the monotonic case, these deformation features do not markedly affect the cyclic cracking process.
