Abstract
A method of repairing an integrally bladed rotor includes removing a portion of the integrally bladed rotor to create a void in an airfoil, completely filling the void with a single replacement material, and laser shock peening the replacement material. Laser shock peening the replacement material imparts mechanical properties in the replacement material substantially the same as those in the forged material.
