Critchlow On cooling rate dependent spallation behavior of α-alumina scale grown by oxidation Loughborough University 2019 Alumina scale Cooling rate Pockets of energy concentration Residual stress Spallation Engineering not elsewhere classified 2019-06-12 08:26:11 Conference contribution https://repository.lboro.ac.uk/articles/conference_contribution/On_cooling_rate_dependent_spallation_behavior_of_-alumina_scale_grown_by_oxidation/9221486 It is hypothesized that dynamic and non-uniform plastic relaxation occurs in α-Al2O3 scale on Fe-Cr-Al substrate during cooling from high temperature, and furthermore, that the non-uniformity of plastic relaxation is related to (1) the variation of residual stress with respect to cooling rate; and (2) the rate of stress relaxation. Based on this hypothesis, a mechanical model is developed which gives accurate predictions for the cooling dependent spallation behavior of α-Al2O3 grown by oxidation.
