Abstract

Segregation behavior of Ti, V, and Hf impurities at antiphase boundaries (APBs) in Ni₃Al is computed and related to the site preference. The effect of relaxation of atomic positions is considered. Using a relationship between site preference and segregation behavior, the effect of other transition metals on APBs is predicted.
