Phase Instability during Low Cycle Fatigue of Steel.
Abstract
Studies of the relationship between martensitic transformation and low cycle fatigue have been carried out with a variety of related austenitic stainless steels. In addition to using composition as a variable, other effects such as test temperature, heat treatment and loading program were studied. Fatigue life under controlled strain amplitude conditions was determined, while the amount of alpha' martensite was continuously monitored. Optical, SEM and TEM metallographic results were used to interpret the mechanical behavior. Some studies on strain aging vs. cyclic deformation of iron and mild steel were also carried out. (Author)
