Abstract
The dynamic properties and atomic configuration of Mg, Mg-Zn, Mg-Zn-Ca and Mg-Zn-Ca-Cu liquid and solid systems were comprehensively studied using ab initio molecular dynamics calculation. The viscosities of an Mg-Zn-Ca alloy were measured from 700 K to 960 K. It was found that Zn and Ca in Mg liquid induce remarkable slowing down of atoms, but Cu acted as a stimulus to the diffusion. Icosahedral short-range orders are most dominant in Mg-Zn-Ca alloys in view of the existence of a majority of 1551 type of bond pairs, âŒ
