Abstract
AZ31 Mg alloy was compressed alternately in two orthogonal directions at room temperature. Many {10\bar{1}1} twins connected by {10\bar{1}2} 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\bar{1}1} and {10\bar{1}2} twin boundaries induced initiation of fracture, resulting in low ductility of the alternately-compressed specimens.
