Load Sharing of the Phases in 1080 Steel During Low Cycle Fatigue

Abstract

By means of x-ray diffraction, the stress response of the individual phases in a 1080 steel were measured. Specimens with pearlitic, spheroidal, and tempered martensitic microstructures were subjected to low cycle fatigue and the stress strain hysteresis loops were separated into components for the carbide and matrix phases. These results show that as the material yields in both tension and compression the carbides take a higher fraction of the load and thus the stress range experienced by the carbide phase is much higher than the matrix during low cycle fatigue.
