Abstract

A post manufacture method and apparatus for reducing residual stresses present within a component. The component includes a substrate, a polycrystalline structure coupled thereto, and residual stresses present therein. The method includes obtaining a component from a component category, determining a critical temperature and a critical time period for the component category at which the component becomes structurally impaired, determining a heat treatment temperature and a heat treatment time period based upon the critical temperature and the critical time period, and heating one or more remaining components from the component category to the heat treatment temperature for the heat treatment time period. The apparatus includes a heater defining a heating chamber and a molten bath positioned within the heating chamber. The components are placed within the pre-heated molten bath and isolated from oxygen during heating to the heat treatment temperature for the heat treatment time period.
