Abstract: A process for manufacturing a component on which in-service stresses are imposed by in-service loading conditions. The process generally entails fabricating the component such that residual stresses are induced in the component that substantially offset one or more primary stresses which would otherwise limit the maximum service life of the component. The residual stresses are induced by creating compressive stresses in the component that extend sufficiently beneath the working surface of the component during fabrication. In order to appropriately attain the necessary residual stresses, the process of this invention includes developing a model of the component, and then applying the in-service loading conditions to the model to determine the in-service stresses on the component. Thereafter, at least one of the in-service stresses is identified as being critical, i.e., a stress that establishes the maximum service life of the component.
