Paper Title:
Computer Simulation of Evolution of Ordering Phases and the Boundaries of Ni-Cr-Al Alloy
  Abstract

Based on the microscope phase-field model,the evolution of atom morphology, the long range order(lro) parameter and concentration can be gotten, and atomic clustering and ordering during the precipitation process of Ni-Cr-Al alloy could be obtained. The Ni-14at.%Cr-15.5at.%Al alloy is studied and the temperature of precipitation are 973K. It was showed that the ordering of both Al and Cr atoms take place simultaneously during the precipitation process of Ni-Al-Cr alloy, Cr atoms transfer to the boundaries of L12 phases, the domain of rich Cr atoms are formed. At the boundaries of L12 phases, Cr atoms may substitute the Al sublattice, and the D022 phases are formed.
