Fig.4. Primary slip systems under two different loading directions (The planes ACD (normal vector is ( $1 ˉ$ 11)) and BCD (normal vector is (1 $1 ˉ$ 1)) 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 [0 $1 ˉ$ 1] and [101] in the slip plane ACD, respectively; BC and BD represent the slip directions of [ $1 ˉ$ 01] and [011] in the slip plane BCD, respectively)Color online(a) along X axis (b) along Z axis
