Short range order in molten Al–Si alloys

We have studied the microscopic structure such as, concentration fluctuation in long wavelength limit (S_CC(0)), Warren–Cowely short range order parameter (α ₁), ratio of mutual and intrinsic diffusion coefficients (D _M/D _id) of molten Al–Si alloy at 1700?K using a statistical model of complex formation on the basis of quasi-lattice theory for weakly interacting systems. The approach used in this article reveals that molten Al–Si alloy at 1700?K is a weakly interacting heterocoordinating system and the alloy is more ordered in the Al-rich end.
