Abstract: A semi-empirical potential for the Al90Sm10 alloy is presented. The potential provides satisfactory reproduction of pure Al properties, the formation energies of a set of Al–Sm crystal phases with Sm content about 10%, and the structure of the liquid Al90Sm10 alloy. During molecular dynamics simulation in which the liquid alloy is cooled at a rate of 1010 K s−1, the developed potential produces a glass structure with lower ab initio energy than that produced by ab initio molecular dynamics (AIMD) itself using a typical AIMD cooling rate of 8*10^13 K s−1. Based on these facts the developed potential should be suitable for simulations of phase transformations in the Al90Sm10 alloy.

Notes: Mikhail Mendelev (Ames Laboratory) noted that the potential "was developed to simulate the solidification/devitrification in the Al90Sm10 alloy." The reference was updated on 13 June 2015.
