The microstructural evolution of Al12Mg17 alloy during the quenching processes

Abstract The processes of rapid solidification for three cooling rates of Al 12 Mg 17 alloy from liquid to solid are simulated using molecular dynamics based on embedded-atom method potentials derived by the force-matching approach. The liquid structures are calculated and the structural factors are in good agreement with experimental data. During each rapid quenching, an amorphous state is obtained, and the microstructures of the liquid, supercooled liquid, and the amorphous states of Al 12 Mg 17 alloy are analyzed using the pair analysis technique.
