Superior ductility in magnesium alloy-based nanocomposites: the crucial role of texture induced by nanoparticles

摘要: In an expansive field of metals, magnesium has been trending late in automobile, aerospace, defense, sports, electronic and biomedical sectors as it offers advantage lightweighting. the realm Mg-based materials, Mg nanocomposites have a good combination specific strength, thermal damping properties, but lack high ductility do not typically undergo large amount uniform elongation. The current work bridges this gap by reporting nanocomposite (Mg–1.8Y/1.5Y2O3) that exhibits significantly tensile 36%. Microstructural characterization revealed striking presence micron-Mg–Y phases nano-Y2O3 particles matrix led to bimodal particle distribution which affected dynamic recrystallization mechanism. It was also observed addition Y2O3 nanoparticles weakened texture nanocomposite. dominating influence weakening over other mechanisms (grain refinement alleviated micro-strain) on plastic deformation/ductility is highlighted, contribution toward enhancement ascertained. contrast previous studies where are known improved strengths, approach can be used develop exceptional.
