Abstract:

A method of enhancing or prolonging the low cycle fatigue life of the bore area of a rotating disk. The method comprises the step of prestressing the bore area by heating the webrim area of the disk, while moderately overspeeding the disk. The heating can be accomplished with the use of induction heating coils which are disposed adjacent the webrim area of the disk. This method, unlike prior art prestressing methods, is simple to perform, is cost effective, and does not compromise the disk or the design of the assembly of which the disk is a component. Author
