Acoustic emission (AE) is a non-destructive experimental technique in which transient elastic waves generated within a material due to sudden and irreversible structural changes are detected and evaluated. It has been established that AE is a viable procedure for monitoring the development of microstructure during thermal cycling of composite materials containing ceramic and metallic phases. Specifically, since dislocation motion and microstructural damage are generally recognized to produce significant AE, there is a possibility of using the AE technique to identify and characterize microstructure changes occurring in composites due to thermal loading and to correlate these measurements with the associated temperature and other testing parameters.
