AbstractAn experimental investigation was carried out to measure two types of various compression paths on the extruded AZ31 Mg alloy rod at room temperature. The first type is a two-stepped compression with vertical radial directions, which was named as RD1-RD2 compression. The second type is that the compression direction is extruding direction and subsequent radial direction, which was named as ED-RD1 compression. The variation on grains orientation and mechanical properties during above compressions were analyzed. The results reveal that large amounts of {10 (1) over bar2} extension twins and {10 (1) over bar2} - {10 (1) over bar2} secondary twins activate during deformation. Besides, many crossed twin boundaries form within grains caused by different twin variants activations. On the whole, twin activation obeys the Schmid law. On the one hand, for the RD1-RD2 compression, the stress-strain curves of the first and second compressions are almost identical. On the other hand, for the ED-RD1 compression, the stress values of the stress-strain curve of the second compression are significantly higher than that of the first compression.
