Abstract

Based on microscopic phase-field model, atomic morphology evolution of the precipitated phases through cycle heat treatment in the Ni₇₅Al_xV_25-x alloy were studied compared with the single-stage aging. The temperature takes greater effect upon the variation of solubility of DO₂₂ phase than that of Ll₂ phase. The coarse particles of Ll₂ phases are broken up through the cycle heat treatment into the fine grains, most of the Ll₂ phases spheroidized. Furthermore, the cause of the breaking up and spheroidizing has been discussed.
