  The high-pressure melting properties of the ternary alloy AlCuSi with
face-centred cubic structure is theoretically investigated using the
statistical moment method. We calculate the melting temperature for the alloy
under pressure up to 80 GPa. The dependence of the melting temperature on the
content of alloying elements is also studied. Our results agree well with
previous experiments, simulations, and other theoretical calculations.
