%X INCONEL725 is a highly corrosion resistant nickel based alloy capable of being age-hardened to high strength levels. The microstructure observations and the phase iden-tification after a standard heat treatment were investigated. The results show thatmary carbide phase TiC, as well as M6C carbide and a little extent MC (mainly TiC)precipitates which nucleate mainly at grain boundaries. An isothermal aging studywas carried out on this alloy for up to 10 000 hours at 593℃. This additional agingdid not affect the tensile strength. However, microstructures show that the thermalexposure has a little additional effect. With increasing the exposure time, the size ofcipitated at grain boundaries have an increased and complex tendency on a few grainboundaries. The experimental results illustrate the excellent structure stability of theage-hardenable IN725 at 593℃.
