Interest on Mg alloys has significantly increased in recent years for weight-critical applications such as automotive. However, several challenges still exist due to the high cost of Mg sheet production and theits limited formability of sheet. Twin-roll casting (TRC) can considerably reduce the cost of sheet production, however, TRC Mg alloys still show strong basal texture similar to like conventionally cast material ones, which negatively influences the formability. Formability can be improved by weakening the basal texture in Mg alloy sheets. The equal channel angular processing (ECAP) method can induce different deformation textures as opposed to the results of conventional sheet rolling. Thus, in this study, the effect of ECAP at 200°C on texture and mechanical flow response of TRC AZ31 Mg alloy was investigated. It has been shown that strong basal texture and flow response of TRC AZ31 Mg alloys can be modified in such a way as to improve formability through different ECAP routes.
