For cold forging applications often high performance PM — tool steels were applied. The tools are cyclically repeated loaded to very high stresses by the forging process. The stresses are often significantly larger than the yield stress. This will result in a local plastic deformation, crack initiation, crack propagation and finally to the failure of the tools.
