Abstract
A method of altering the properties of a solid material by varying the temperature of the solid material either before or after or both before and after laser shock processing the solid material. In addition, the method may be repeated for successive laser shock processing of the solid material.
Claims18
A method of altering the properties of a solid material by providing shock waves therein, comprising the steps:
- changing the temperature of the solid material to a first increased temperature above room temperature;
- introducing compressive residual stress in the solid material at said first temperature by laser peening.
