Correlation between diffraction and viscosity data for Bi–Ga molten alloys

Bulletin of Materials Science volume 35, pages83–87(2012)Cite this article

Abstract

Structure of Bi\(_{\boldsymbol{100-x}}\)Ga\(_{\boldsymbol{x}}\) molten alloys containing 38·5, 50, 70 and 91·5 at. % Ga has been studied by means of X-ray diffraction method and compared with viscosity measurements data. Significant changes in the structure factor profile were observed in vicinity of the concentration 70 at. % Ga. The dynamic viscosity coefficient was calculated by use of a statistical atomic distribution model and a Born–Green kinetic theory. The concentration dependence of viscosity is in agreement with change of structure parameters obtained from diffraction data.
