Investigation of the mechanical and corrosion performance of hot-extruded Mg-Li-Y alloys designed for biomedical applications

Original language description

This study investigates the combined effect of Li and Y alloying on the mechanical performance and corrosion resistance of hot-extruded magnesium alloys. Five alloys from the Mg-Li-Y system with varying amounts and ratios of Li and Y, namely the single-phase matrix Mg-2Li-2Y, Mg-2Li-4Y, Mg-4Li-2Y, Mg-4Li-4Y, and the dual-phase matrix Mg-8Li-1Y (wt.%), were processed by hot extrusion. The presented microstructural investigation revealed varying levels of Y supersaturation, arising from the rapid air cooling after extrusion. The non-equilibrium distribution of Y alloying atoms and the degree of Mg-Y secondary phase formation were found to be substantially influenced by the presence of Li in the hcp matrix, in contrast to the previously investigated ECAPprocessed materials. The microstructural differences among the investigated alloys governed their performance in the mechanical and corrosion performance testing, which were conducted as a preliminary screening of their suitability for biomedical applications. Especially the best-performing Mg-4Li-4Y alloy benefited from the synergic effects of Li and Y alloying and the non-equilibrium microstructural states arising from the extrusion process, achieving an excellent balance of strength and ductility combined with a comparatively low corrosion rate in the preliminary degradation experiments.
