Abstract

The atoms site preference in the Al3Ti-Zn system has been studied using H. Rietveld method. The L12 Ti(Al, Zn)3 particles evolve in a ZnAl25 melt from the L12TiZn3 particles in the ZnTi4 master alloy. It is found that Zn is replaced by Al during the transformation TiZn3 → Ti(Al, Zn)3. In the evolving fcc L12 Ti(Al, Zn)3 phase Ti occupies (0, 0, 0) position while Al and Zn occupy (0, 0.5, 0.5) position, similarly to Al and X in the Al3Ti-X systems, where X = Ni, Cr, Mn, Cu, Ag, Pd [1, 2].
