摘要
Simulations are performed on atom substitution behaviour in Ni75Al25-xCrx. alloys based on a microscopic phase-field model at 873K. The ordering of both the Al and Cr atoms takes place simultaneously, Cr occupies both the Al and Ni sites with a preference for the Al sites, and Cr and Al atoms together occupy the beta-sites, and the complex gamma' Ni-3(Al1-xCrx) (L1(2) structure) phases are formed during the precipitation. At the ordering boundary of L1(2) phases, Cr atoms occupy the Al sites, then Ni3Cr phases are formed.
