Abstract

Methods and apparatuses for processing materials to enhancing the material's surface strength, improving the material's cyclic and thermal stability of microstructures, and extend the material's fatigue performance. Embodiments include laser shock peening at material temperatures that are moderately elevated (from the material's perspective) above room temperature. Alternate embodiments include laser shock peening at very cold (cryogenic) material temperatures. Still further embodiments include laser shock peening while covering the surface of the material being processed with an active agent that interacts with the laser energy and enhances the pressure exerted on the surface.
