Abstract

The article presents tests results of the influence of Li and Ca content on the microstructure and properties of Mg-4Li-1Ca (LX41) and Mg-8Li-2Ca (LX82) alloys after extrusion process. Achieved microstructures of magnesium alloys after extrusion were compared with microstructure after casting and homogenisation. An analysis was conducted of the microstructure in initial condition and in condition after plastic deformation with the use of techniques of light and scanning microscopy. Presented results show the mechanical properties marked in static extrusion test in room temperature. It was stated that alloy Mg-4Li-1Ca (LX41) is characterised with better plasticity than the alloy Mg-8Li-2Ca (LX82).

Keywords: Mg-Li-Ca alloys, microstructure, extrusion process, electron microscopy, static compression test
