Specimens of Inconel-X alloy solution-treated at 2050 deg F and aged for periods of 1, 10, 100, and 1000 hr it 1200, 1400, and 1600 deg F have been examined by electron microscopy and by electron and x-ray diffraction. Four minor phases were identified: titanium nitride, e intermetallic gamma /sup '/ phase. The two nitrides were found in all of the aged specimens and the solution- treated alloy, the gamma /sup '/ phase formed at all aging temperatures, while the M/sub 23/C/sub 6/ carbide formed only on aging at 1200 and 1400 deg F/. Variations in the hardness, rupture strength, creep strength, and yield strength of the alloy have been shown to be related to variation in the size and distribution of the particcles of the gamma ' phase maximum values of these properties occuring when there is a of dispersion of the particles prevails.
