Computer simulation of Cr atom substitution behavior for ternary alloy Ni-Cr-Al
Simulations are performed on Cr atom substitution behavior in Ni-Cr-Al alloy based on microscopic phase-field model at 873K. It was showed that the substitution of Cr is affected by Cr and Al component and limits of occupation probabilities of Cr in L12 phases are present. The precipitates are single L12 phases when the component is lower, Cr atoms substitute the Al sublattice in L12 phases, and both of Al and Cr occupy the β-sites and complex phases Ni3 (Al1-xCrx)are formed.
