摘要	New Mg-2.0Zn-0.8Gd alloy sheet showing non-basal texture with double peaks tilting +/- 42 degrees from the normal direction towards the transverse direction were fabricated by common rolling process. The sheet exhibited high room-temperature elongation of 43% along the trans verse direction. Tensile tests were carried out at room temperature aiming to explore reasons for the high ductility through investigating deformation modes by characterizing microstructure and texture evolution. The results indicated that {1012} twinning and basal slip played important roles during the uniform elongation due to their large Schmid factor, while non-basal slip played a significant role during the late deformation and contributed to the high ductility. The brittle fracture of large particles led to the failure of the sheets. It is proposed that that the high ductility of the sheet with non-basal texture is attributed to the prevalence of {10 (1) over bar2} twinning and basal slip combined with the absence of{10 (1) over bar1} twinning and the low volume faction of large brittle particles.
