Claim 0:
1. A method for remotely desensitizing a metal alloy, the method comprising:
exposing a surface of a metal alloy to a controlled scanning laser beam irradiation output by a laser and having an average laser output power over 10 W or an output laser pulse energy over 10 mJ;
wherein the surface of the metal alloy is exposed to the scanning laser beam irradiation directly or through a coating layer including a paint, a nonskid layer, or other coating layer(s);
wherein a distance between an output window of the laser beam irradiation and the metal alloy is between about 0.5 m to about 100 m; and
wherein the scanning laser beam irradiation is controlled to scan across a portion of the surface of the metal alloy comprising two or more locations and heat the portion of the metal alloy to reach an average temperature between a solvus temperature and a softening/annealing temperature of the metal alloy, and then using a local heating effect produced by the scanning laser beam irradiation to further dynamically and locally increase the temperature of a desired location in the metal alloy to desensitize the metal alloy.
