Abstract
A superalloy component heat treatment method using controlled induction heat treatment. The method being adapted to controllably generate a coarse grain microstructure region within the component from a fine grain microstructure metallic component. The method further being adapted to controllably form precipitates within the desired region in order to achieve a desired hardness therein. A single piece alloy component having a controlled core region and a controlled peripheral region. The controlled core region defining fine metallurgical grains and adapted to provide a desired fatigue resistance. The controlled peripheral region defining coarse metallurgical grains and adapted to provide a desired creep resistance.
