Influence of crystal orientation on the thermomechanical fatigue behaviour in a single-crystal superalloy

In this study, the influence of crystal orientation on the thermomechanical fatigue (TMF) behaviour of the recently developed single-crystal superalloy STAL-15 is considered, both from an experimental and a modelling perspective. Experimental results show that there is a strong influence of the elastic stiffness, with respect to the loading direction, on the TMF life. However, the results also indicate that the number of active slip planes...
