Paper Title:
Simulation of V Atom Substitution Character in Ni-Al-V Alloy
  Abstract

Simulations are performed on atom substitution character in Ni-Al-V alloy based on microscopic phase-field model at 1046K. It was showed that the ordering of both Al and V atoms take place simultaneously during the precipitation process of Ni-Al-V alloy, V atoms substitute the Al sublattice in L12 phases, and they prefer β-sites to α-sites. Both of Al and V occupy the β-sites and complex phases Ni3(Al1-xVx)are formed; V atoms substitute the Al sublattice, the D022 phases are formed at the boundary of L12 phases.
