Spallation of oxides grown on TP347H FG in air-saturated steam at 923 K for 50–1000 hours was investigated using a newly developed technique termed: Simultaneous Thermographic and Optical Recording Media Examination (STORME), recording the temperature disturbance resulting from delamination and spallation, during cooling, using Infra Red and video cameras. For the first time, the radius of the delamination site was measured experimentally at the point of buckle formation and followed during growth to the point of spallation. Collection of the exact spalled fragment was possible. The strain energies at each stage were calculated and a Spallation Map constructed.
