Selected Residual Effects Upon Temperature Transitions
Developments of some fundamental aspects associated with crack tip shielding potential, phase stability and damage assessments.
Considerations as related to interactive effects and their reflection on the intrinsic mechanical properties at low temperatures.
Accordingly, the current investigation objectives are centered on illuminating some of these issues by following experimental findings evaluation. The experimental initiative in stationary and subcritical growing cracks include load interaction effects mainly in BCC systems and environmental interactions in metastable austenitic stainless steels.
More refined views on residual or contact stress effects, process zone formation and cyclic crack growth transients are proposed. In addition, environmental interactions are described, expressing some phase stability concerns. Finally, the role of the time factor via thermal activation approach is discussed with emphasis to low temperature material performance assessments.
