A comparison of high temperature fatigue crack propagation in sub-solvus heat treated turbine disc alloys
A comparison of high temperature fatigue crack propagation in sub-solvus heat treated turbine disc alloys
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.

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.
