Abstract
Thermal fatigue measurements have been carried out with aligned eutectic Co-Cr-Al-C alloys. The following were observed: (a) ripening; (b) partial carbide transformations; (c) irreversible strain effects. These effects have been evaluated qualitatively, and to explain the irreversible strain a model has been proposed in which both the differential thermal expansion between matrix and fibre and the deformation rate dependence of yield stress are considered.
