- 論文の詳細を見る
The crystal structure of CuAu_<1-y>Pt_y(0≤y≤1) was studied by X-ray diffractometry. In this alloy system, an L1_0-type ordered state (0 ≤y<0.42), a two-phase state of L1_0+L1_1(0.42<y<0.96) and an L1_1-type ordered state (0.96≤y≤1) were observed. The internal energy of the quasi-binary AB_<:1-y>C_y having the L1_0- and L1_1-type structures is expressed in terms of the Morse potential function. The potential parameters were determined so as to produce the best fit to the observed change with composition in the axial ratio c_0/a_0 of the L1_0-type structure. Using these parameters, the lattice constants of the respective phases were calculated.
