The high potential at the elevated temperatures and large relaxation resistance and higher tensile properties to higher temperature of 1300oF. For the high potential at the elevated temperatures and high resistance to relaxation, though the larger tensile features of 1300oF. The inconel alloy X – 750 sheet and plate are provided for the furnace cooling precipitation processing of 1300oF for eight hours, furnace cooling  of 1150oF that holds at 1150oF for the total precipitation processing time of 18 hours.

As compare to the heat processing of 1300oF for 20 hours and furnace cooling precipitation that results in increasing the tensile potential and yield force that is increased up to 1300oF. The ductility is reduced though not apparently. The minor difference in the stress rupture characteristics at 1200oF, 1350oF and 1500oF is made by following the double treatments. The high temperature tensile features of annealed and furnace quenched precipitation treated are shown in the below table:

1000 155.0 116.0 25.0
1100 145.0 116.5 9.0

The rupture period of inconel X-750 at the different temperatures of 1200oF, 1350oF and 1500oF are shown in the below table:

Thickness Test Conditions, oF/ksi Rupture Life, hours
