“…We first calculated the activities of Sn-Pb alloys at 773K with Thermo-Calc TM . We then calculated the activities using theoretical values at other temperatures 9) and the following equations under the assumption that w/z is constant 10) . Figure 10 shows the theoretical curves obtained by the two calculation methods and the experimental data obtained in this study.…”

We improved the method of measuring method of interdiffusion coefficients using the Foton shear cell technique and stable density layering by adding the normalization of the measured concentration, reducing the segregation in the alloys, and improving the fitting method of the theoretical diffusion formula. We measured interdiffusion coefficients of Sn-Pb alloys using two different diffusion pairs (Sn and Sn-10at%Pb, Pb and Pb-10at%Sn) at 773K and investigated the dependence of diffusion coefficients on the solute concentration. The measured values agreed well with the theoretical curve obtained using Darken's equation. Therefore, we supposed that Darken's equation is also applicable to diffusion in liquid.

“…The effect of atomic size mismatch volume on S cc (0) in the long-wavelength limit is also considered. The size ratio is To obtain a clear picture of the nature of segregation and ordering in the binary liquid alloys, another quantity known as the Warren-Cowley CSRO parameter, α 1 , [6,24,29] is computed. This is related to the S cc (0) by…”

The phase diagrams of Fe-Pt and Ni-Pt liquid alloy systems show the existence of FePt and NiPt intermetallic compounds, respectively, in their solid intermediate states, and the associative tendency between unlike atoms in these liquid alloys has been analysed using the self-association model. The concentration dependences of mixing properties such as the free energy of mixing, G M ; the concentration fluctuations, S cc (0), in the long-wavelength limits; the chemical short-range order (CSRO) parameter, α 1 ; as well as the chemical diffusion, enthalpy and entropy of the mixing of Fe-Pt and Ni-Pt liquid alloys have been investigated to determine the nature of ordering in the liquid alloys. The results show that heterocoordination occurs in the alloys at all concentrations. The effect of CSRO on S cc (0), chemical diffusion, D, and the order parameter, α 1 , has been considered. The ordering phenomenon in the liquid alloys is also related to the effect of the atomic size mismatch volume on S cc (0).
