WANG, S. ... et al., 2017. The mechanics of interface fracture: (4) room temperature spallation of α-alumina films grown by oxidation. IN: Proceedings of the 14th International Conference on Fracture, Rhodes Greece, 18-23 June 2017.
An analytical mechanical model is developed to predict the room temperature spallation
behavior, including the separation nucleation, stable and unstable growth, and final spallation
and kinking off, of α-alumina films grown by oxidation on Fe-Cr-Al alloy. The predictions
from the developed model are compared against experimental results and excellent
agreement is observed. The work reveals a completely new failure mechanism of thin layer
