Heat treatment method and components treated according to the method

摘要

Disclosed herein is a method of treating a component comprising solution treating the component for a period of about 4 to about 10 hours at a temperature of about 1750 to about 1850°F.; cooling the component to a temperature of about 1580 to about 1650°F. at an average rate of 1°F./min to about 25°F./min; stabilizing the component at about 1580 to about 1650°F. for a period of about 1 to about 10 hours; cooling the component to room temperature; precipitation aging the component at a first precipitation aging temperature of about 1275 to about 1375°F. for about 3 to about 15 hours; cooling the component at an average rate of 50 to about 150°F./hour to a second precipitation aging temperature of about 1100 to about 1200°F. for a time period of about 2 to about 15 hours; and cooling the component.
