摘要：
The microstructure of transverse and longitudinal sections of a commercial AZ91 alloy processed by equal-channel angular pressing was examined by transmission electron microscopy. A high dislocation density and large number of deformation twins were observed in the investigated material. The {1 (1) over bar 02}(matrix) parallel to {0 (1) over bar 12}(twin) twinning system was determined by selection area diffraction patterns obtained from the twin and matrix. Transmission electron microscopy analyses also revealed that the twins interacted with each other and pile-ups of dislocations occurred near the twin boundary.
