A repaired component with improved material and mechanical properties and a method of improving the properties of a repaired component are provided. The repaired component comprises a body, a repaired area integral with the body, and an area of compressive residual stress wherein the area of compressive residual stress comprises at least a portion of the repaired area. One method for improving the fatigue performance, foreign object damage tolerance, and resistance to stress related failure mechanisms of a repaired component includes inducing a designed residual compressive stress distribution with a controlled amount of cold work in the repaired area to offset high-applied tensile stresses and stresses introduced as a result of the repair procedure as well as to improve the properties of the material added to the component during the repair. |
