Magnesium is the lightest engineering metal. Replacing steel with Mg based materials in automotive applications would lead to more than 40% weight reduction which significantly boost fuel efficiency. However, conventional Mg alloys typically suffer from low strength and poor deformability due to very few slip systems and easy twinning. Alloying Mg with other materials and microstructural engineering are promising approaches to increase ductility and strength of Mg According to Wang et al. interfaces with low energy and high coherency may effectively constrict the nucleation of twins in Mg In this work, the microstructure of Mg nano layers and nano rods were examined after deformation to determine the dominant deformation mechanisms
