E. Cabet et al., L1(2)-DO22 COMPETITION IN THE PSEUDOBINARY (PT, RH)(3)V,PT-3(V, TI), AND (PD, RH)(3)V ALLOYS - PHASE-STABILITY AND ELECTRONIC-STRUCTURE, Physical review letters, 76(17), 1996, pp. 3140-3143
It is shown that the progressive substitution of a small amount of Pd
and Pt by Ph in Pd3V and Pt3V whose ground state is the DO22 structure
, or the substitution of V by Ti in Pt3V, stabilizes a few simple long
period structures and finally the L1(2) structure. This occurs for an
electron per atom ratio about 8.6, in full agreement with accurate el
ectronic structure calculations.
