Fig. 1 Lattice structure of magnesium single crystal: a a pyramidal I (π1) plane is marked by light green; b two adjacent slip planes of π1: plane indicated by light red with , and plane indicated by light blue with ; c atoms configuration of π1 super-planes and possible slip vectors
Fig. 3 The projection of γ surfaces obtained using Liu EAM potential: a γ surface of plane. The straight slip path and the minimum energy path are marked by black solid and dash lines, respectively; b, c γ surfaces of and planes. The minimum energy paths along different slip planes and directions are marked by red and purple lines, respectively
