Fig.4. Primary slip systems under two different loading directions (The planes ACD (normal vector is (ˉ111)) and BCD (normal vector is (1ˉ11)) are the primary slip planes, and the red edges of the Thompson tetrahedron are the primary slip directions, AC and AD represent the slip directions of [0ˉ11] and [101] in the slip plane ACD, respectively; BC and BD represent the slip directions of [ˉ101] and [011] in the slip plane BCD, respectively)Color online(a) along X axis (b) along Z axis
