Abstract

Laser shot peening, a surface treatment for metals, is shown to induce compressive residual stresses of over 0.040 inch to provide improved resistance to vairous forms of failure. A solid state laser technology employing Nd:glass slabs and phase conjugation enables this process to move into high throughput production processing. Details of the technology are discussed.
