1. Introduction. Austenitic materials usually have a good ductility, which makes it possible to cold- or hot-deform them. In some circumstances, however, this ductility can be reduced at temperatures typically between 0.5 and 0.8 T M (melting temperature). This phenomenon is referred to as a "ductility trough", "loss of ductility", …
