Abstract
The influence of texture on deformation behavior has been investigated for conventionally rolled magnesium slab and rolled twin roll cast (TRC) magnesium strip in form of sheets. The Mg-Zn-Rare earth alloy sheets were deformed at room temperature with the tensile axis oriented in the rolling (RD), 45° and the transversal direction (TD). The basal pole intensity aligned with the sheet normal direction is lower for the conventionally rolled sheet by comparison with the rolled TRC strip. Higher yield strength (YS) in the RD than in the TD for conventionally rolled sheet and higher YS for TD than RD in rolled TRC strip was observed. The acoustic emission (AE)analysis correlates the microstructure and the stress-time curves to the active deformation mechanisms. This aspect relates to the activity of the basal slip and tensile twinning, particularly during TD tension, which corresponds with the AE activity.
