چکیده انگلیسی
In the recent years, magnesium-lithium (Mg-Li) alloys have attracted considerable attention/interest due to their high strength-to-density ratio and damping characteristic; and have found potential use in structural and biomedical applications. Here the mechanical behavior of novel Mg-9Â wt.% Li-7Â wt.% Al-1Â wt.% Sn (LAT971) and Mg-9Â wt.% Li-5Â wt.% Al-3Â wt.% Sn-1Â wt.% Zn (LATZ9531) alloys is reported. Both, as cast and thermomechanically processed alloys have been studied which possess dual phase microstructure. Nanoindentation data have been utilized to envisage the elastic modulus of alloy via various micromechanics models (such as rule of mixtures, Voigt-Reuss, Cox model, Halpin-Tsai and Guth model) in order to estimate the elastic modulus. Object oriented finite element modeling (FEM) has been performed to predict stress distribution under tensile and compressive strain state. Close match between Halpin-Tsai model and FEM results show the abridgment of nano length scale property to evolution of microscopic stress distribution in novel LAT971 and LATZ9531Â Mg-Li-Al based alloys.
