The results showed that the cyclic stress-strain (CSS) curve displayed a double plateau region in the plastic strain range of 1.80 × 10-4 － 2.56 × 10-3. The plateau saturation axial stresses were 62 - 64 MPa and 70 - 71 MPa respectively at axial plastic strain range of 1.80× 10-4－ 1.35× 10-3 and 2.04× 10-3 － 2.56× 10-3. The effects of component crystal orientation on the slip characteristics, saturation dislocation patterns and CSS curve were discussed.
