AbstractAbstract
[en] The thermal aging of Ni-Cr-Mo-Fe Alloy (Hastelloy Alloy X) at 10000, 12000, 14000, and 16000F (5380, 6490, 7600, and 8710C) for times up to 15,000 h is discussed together with the associated changes in room-temperature impact toughness properties. Effects of 10,000-h aging on room-temperature and elevated-temperature tensile properties, and stress-rupture properties were also evaluated. The alloy exhibits a substantial drop in room-temperature tensile ductility, while elevated-temperature tensile ductility was relatively unaffected by the aging. Stress-rupture properties, while affected by the 16000F (8710C) aging, were relatively unaffected by the lower aging temperatures. The correlation between mechanical properties and microstructure is discussed
