The AM30 Magnesium alloy is a potential candidate for the next-generation automobile and aerospace structural components due to its high specific strength and low density. Its usage will reduce carbon emission in the atmosphere and thus the environmental impact of motored vehicles. However, AM30 has low ductility at ambient temperature and possess high anisotropy owing to its hexagonal closed packed structure. Due to limited dislocation slip activities at ambient temperature, {101 ̅2}〈1 ̅011〉 extension twins (ET) play a predominant role during deformation. In this work, experimental investigation using ex-situ electron backscattered diffraction and viscoplastic self-consistent based all twin variant model were employed to decipher the strain-hardening behaviour, microstructure evolution, including volume fraction evolution of each ET-variant, and texture evolution during deformation in AM30. The integration of modelling with the experiments provided in-depth insight into the deformation behaviour. |
