Abstract

In this study, the microstructure, residual stress and fatigue behavior of Hoeganaes' Ancorsteel 4300 sintered steel were characterized. Samples were tempered at either 205°C or 315°C and then machined by conventional grinding. The effects of residual surface stress (measured by XRD) on the fatigue behavior were studied by either application of a stress-relieving heat-treatment after machining or by polishing away the machined surface. Based on this study, samples tempered at 315°C had slightly higher fatigue strengths than samples tempered at 205°C. Although significant compressive stresses were induced by machining on the surface of samples, these residual stresses did not affect the fatigue behavior. Rather, the fatigue behavior was controlled by porosity inherent to these sintered steels.
