An as-cast AM30 Mg alloy was homogenized at 400 °C for 24 h and rolled at 350 °C by symmetric rolling (SR), asymmetric rolling (ASR), and asymmetric rolling combined with reverse rolling (ASR + RR). The grain size marginally decreased from SR to ASR to ASR+RR processes. The low-angle grain boundaries (LAGBs) percentage was in the order ASR+RR > ASR > SR and maximum intensity of basal texture was in the order ASR+RR < ASR < SR. The tensile properties of the hot-rolled sheets were in the order ASR+RR > ASR > SR. Thus, the tensile properties of 0.2 PS = 224 ± 1 MPa, UTS = 276 ± 3 MPa, and El = 8.2 ± 0.4 with minimum anisotropy were obtained for ASR+RR sheet. The higher strength of ASR+RR sheet is attributed to a higher percentage of LAGBs resulting in greater strain hardening and higher El and minimum tensile anisotropy is attributed to the weaker basal texture. © 2022, The Minerals, Metals & Materials Society.
