background
● Failure accidents by deterioration of infrastructure
● Fatigue is the main cause of failures in metallic structures.
summary
● Implementation of fatigue crack healing of 90%
● Implementation of static tensile strength of 75%
● Fatigue crack healing due to elimination of oxide film by vacuum heating, plasticity-induced crack closure and atomic diffusion.
