Notes:
The atoms site preference in the Al〈sub〉3〈/sub〉Ti-Zn system has been studied using H. Rietveldmethod. The L12 Ti(Al, Zn)〈sub〉3〈/sub〉 particles evolve in a ZnAl25 melt from the L1〈sub〉2〈/sub〉TiZn〈sub〉3〈/sub〉 particles in the ZnTi4 master alloy. It is found that Zn is replaced by Al during the transformation TiZn〈sub〉3〈/sub〉 → Ti(Al,Zn)〈sub〉3〈/sub〉. In the evolving fcc L12 Ti(Al, Zn)〈sub〉3〈/sub〉 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 Al〈sub〉3〈/sub〉Ti-X systems, where X = Ni, Cr, Mn, Cu, Ag, Pd [1, 2]
