Description/Abstract

This paper presents the results of high temperature fatigue tests carried out in air at 725°C on four different materials: N18, RR1000, Udimet 720Li (U720Li) and U720Li Large Grain (U720Li LG) variant. The influence of composition, sub-solvus heat treatments, together with varied cooling rates on grain size and gamma prime size and distribution on fatigue crack propagation behaviour are compared and contrasted.
