摘要
AZ31 Mg alloy was compressed alternately in two orthogonal directions at room temperature. Many [10 (1) over bar1] twins connected by [10 (1) over bar2] twins were found in the alternately-compressed specimens. The compressed specimens exhibited much lower ductility than the non-compressed specimen, and their ductility decreased with an increase in the number of compression. It is therefore suggested that many triple junctions of [10 (1) over bar1] and [10 (1) over bar2] twin boundaries induced initiation of fracture, resulting in low ductility of the alternately-compressed specimens.
