The mechanics of interface fracture: (4) room temperature spallation of α-alumina films grown by oxidation
conference contribution
posted on 2017-05-03, 10:08 authored by Simon Wang, Christopher HarveyChristopher Harvey, Bin Wang, Andrew WatsonAndrew WatsonAn 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
materials.
