| Abstract: | By SAED and trace analyses techniques,{0 1 2}twins in cast Mg-0.5Zr,Mg-5.7Zn,and Mg-5.6Zn-0.5Zr alloys were studied in this paper.The results show that the twins are present in all three cast alloys.In the shape of lenticular plate,the twins have a large scale of twinning,and the twinning plane are{0 1 2}.The method of the matrix is applied to analyze the SADPs of the twins. |
