The properties of a large forged disc of Inconel X alloy at room temperature, 1200, 1350, and 1500 degrees F were studied in order to determine the level of properties obtainable in a forging of the type required for the rotor discs of gas turbines. The disc was tested in the solution-treated and aged condition.
