Abstract
Sustained loading was applied to alloy 783 subjected to a non-standard heat treatment, annealing plus γ′ aging, at elevated temperature. The existence of damage zone ahead of the crack tip was identified and propagation rate of the damage zone was correlated to the sustained loading crack growth rate. The formation of damage zone was ascribed to stress accelerated grain boundary oxidation.
