Mechanical properties of three new high manganese stainless steels for thermonuclear fusion applications
The present work deals with the study of the room temperature tensile and rotating bending fatigue properties of three new Cr-Mn (and low Ni) austenitic steels, developed as low activation structural materials for future thermonuclear fusion applications. The fatigue limits of the three alloys are quite different; this can be explained by comparing the monotonic and cyclic tensile properties, microstructures, S.E.M. analysis of the ruptured surfaces and the micro-hardness profile of the fatigued cross-section. Consideration of cyclic stress-strain behaviour and appropriate strain-gauge measurements supports calculations of effective stress distributions in fatigue tests.
