  In this work we explore the mechanical response of Mg-Nb multilayered nanocomposites as a function of decreasing layer thickness. Layers of Mg and Nb, with individual layer thicknesses varying from 5 to 50 nm, were synthesized using physical vapor deposition. Transmission electron microscopy (TEM) and X-Ray diffraction (XRD) studies reveal that at lower thicknesses of ~5 nm Mg undergoes an interface strain induced phase transition from hexagonal close-packed (HCP) to a metastable body centered cubic (BCC) structure. Using a combination of indentation testing and micro-pillar compression experiments – where the multilayers were tested in 3 different orientations: with interfaces oriented normal, parallel and inclined 450 to the loading axis – we analyze the elastic and plastic anisotropy of this hitherto unstudied BCC Mg structure. These studies reveal BCC Mg to be super-strong and more ductile than its HCP counterpart, suggesting significant implications for potential lightweight aerospace and automotive applications.
explanation: The document is an abstract from a 2017 TMS Annual Meeting & Exhibition, focusing on the mechanical properties of Mg-Nb multilayered nanocomposites. It describes the synthesis and testing methods used to study the phase transition and mechanical behavior of these materials, particularly the transition of Mg from HCP to BCC structure at lower thicknesses. The abstract does not contain any math questions or answers.
