Heat treatment methods for multiphase superalloys

Abstract

Methods are provided for heat treating a component comprised of a multiphase superalloy, along with components formed from the methods. The method includes heat treating the component at a predetermined solution temperature for a predetermined solution time. Thereafter, the component is cooled from the predetermined solution temperature for a predetermined air transfer time in the presence of air, a gas, or a mixture of gases. Thereafter, the component is actively quenched. The predetermined air transfer time is sufficiently long such that a predetermined internal location cools to a temperature that is below the maximum quench temperature before actively quenching the component.
