Abstract
A method for forming gear teeth of a high performance gear is accomplished by shaping the carburized gear tooth surface while the gear blank is held at a uniform temperature in the metastable austenitic condition above the start of the martensitic transformation temperature of the carburized case and then allowed to air cool so that the gear tooth surface will be transformed into very fine grain martensite.
