Popis:	Considering the thermomechanical aspect of deformation leads also to the prospect of monitoring thermal emission as an indirect measure of dislocation activity. In this respect it may be considered to be analogous to acoustic emission and so could be viewed as a possible tool for assessing the damage state of components. With this in mind, a damage assessment was carried out on three identically sized and shaped specimens cut from fractured alloy 800H pipe that had been held under a tensile creep stress of 42 MPa at 900°C, failing after 122 h
