The article presents tests results of the influence of hot extrusion process on the microstructure and mechanical properties of alloy Mg-4Li-1Ca. Materials for tests were ingots which included in their chemical composition, apart from Mg and Li as the basic ingredients, such chemical elements as calcium in the amount of 1% mass. Alloy Mg-4Li-1Ca was achieved in the process of smelting in the shielding gas atmosphere (argon) and then casting into graphite moulds. Before the process of straining the ingots underwent 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. The paper presents results of tests of mechanical properties marked in static compression tests in room temperature.Keywords: Mg-Li-Ca alloys, microstructure, hot deformation, extrusion process
