The structure of liquid Bi-Zn alloys with miscibility gaps

Neutron diffraction experiments have been applied for liquid Bi-Zn alloys. The structure factors of this system along the liquidus curve have been obtained and its temperature dependence above the critical temperature, where the miscibility gap closes, is also examined. A remarkable change in the structure factor has been observed around 80 at% Zn, which composition corresponds to that of maximum critical temperature. This concentration variation of the observed structure factors has been discussed in view point of the thermodynamic properties. (author)
