In this work, we report a texture dependent shifting behavior of neutral layer in bending of a Mg-3Al-1Zn(AZ31) alloy. The underline mechanism is revealed based on microstructure examinations, and is correlated to the yield asymmetry between the inner and outer regions. Then, a pole figure is built based on extensive viscoplastic self consistent (VPSC) simulations, showing the trend of neutral layer shifting with texture. This is helpful for designing the stamping process of magnesium alloys. (C) 2019 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
