Zigzag Dissociation Mode of 〈c + a〉 Dislocations on the Plane in Magnesium Alloys

Figure 3

(a) Sliding pathway of 〈c + a〉 dislocation by the zigzag dissociation mode involved shuffling motion. The length of leading partial dislocations when the c/a ratio is equal to (b) 1.624 and 1.633. (c) The zigzag dissociation modes of Mg-Y alloy. Orange, green, and cyan spheres indicate type A Mg atoms, type B Mg atoms, and Y atom, respectively.
