Twin-roll-cast Mg-3Al-0.4Mn (mass%) alloy was continuously rolled at a warm temperature, and the room-temperature stretch formability, tensile properties, microstructures, and texture of the annealed sheets were investigated. The sheet exhibits large Index Erichsen values over 8mm due to the formation of a ring-like texture feature where the basal poles are oriented ~25° from normal direction to all direction. Fine grain structure with an average grain size of ~7um could be obtained as well, so the sheet shows moderate 0.2 % proof stress of ~160MPa and large elongation to failure over 25 % in both rolling and transverse directions. These properties could be obtained via industrially viable rolling processing which consists of homogenization, warm-temperature rolling, and annealing. This indicates that the developed alloy sheet will broaden the applications of wrought Mg alloys in automotive industries.
