Crack-Healing in Metals

The healing of cracks in metallic components fundamentally involves the exchange of material and energy within an open system. The processes involved include welding and laser repair, various heat-treating techniques, hot plastic deformation, plasma spraying, electro-healing, electroplating, gas carbonitriding, friction stir welding, electric current-pulsing, thermo-mechanical coupling, filling of cracks via oxide formation, flash hot isostatic pressing, and various ultrasonic methods. The book describes the various techniques, their advantages and disadvantages.
