Abstract

The site preferences of Cu and Ge in Ni₃Al with an Ll₂ structure have been investigated by atom probe field ion microscopy (APFIM). The fraction of Cu atoms at the Ni sites was determined to be 94% in the case of the Ni₇₅Al₂₃Cu₂ alloy. On the other hand, the fraction of Ge atoms at the Ni site of the Ni₇₆Al₂₃Ge₁ alloy was determined to be 11%.
