abstract

  • The liquid structure of Al-Si hypoeutectic binary alloys with and without the addition of 0.04 wt.% Sr was characterized by diffraction experiments using a high energy X-Ray (Synchrotron) beam source. The diffraction data for all the alloys were obtained at various melt temperatures. Reverse Monte Carlo (RMC) analysis was carried out using the diffraction experimental data to quantify the partial pair distribution function (PPDF). Further, the partial pair distribution function and the liquid atomic structure information were used in a semi empirical model to evaluate the viscosity of these liquid alloys at various temperatures.
