Magnesium is the lightest of all the engineering metals. Replacing steel structural materials with Mg-based materials in automotive applications would boost fuel. 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, Mg-metal multilayered nanocomposites will be produced by melt spinning procedure and the layers’ mechanical properties will be examined by picoindentation. Meanwhile, plastic co-deformation of the layers can be designed by crystallographic theory and multiscale modelling to achieve fine nanolaminate microstructure in bulk Mg alloys.
