Abstract

The fatigue characteristics of sintered materials have been investigated by determinating the S-N curve, the fatigue crack propagation rate da/dN and fatigue threshold △k_th of N-110 sintered steel by rotating bending fatigue testing machine. The explanation of the influence of porosity on various fatigue properties and the relations between heat treatment and fatigue properties have been discussed.
