Solidification Characteristics of Mg-Li-Al Alloys

The six Mg-Li and Mg-Li-Al alloys in as-cast state namely Mg-4.5%Li, Mg-9%Li, Mg-12%Li, Mg-4.5%Li-1.5%Al, Mg-9%Li-1.5%Al and Mg-12%Li-1.5%Al were prepared and analysed. These alloys have been subjected to the thermal analysis (thermal derivative-analysis and dilatometry study), and the subsequent thermal assessment, mechanical properties and microstructures were studied. The heating and cooling dilatometric curves characterise by a linear reduction (alloys with 12wt.% of Li) and linear increase (alloys with 4.5wt.% of Li) in coefficient of linear thermal expansion as a function of temperature. No transitions in the solid state occur. Based on results of thermal derivative analysis a crystallisation process of Mg-Li and Mg-Li-Al alloys was proposed. Addition of aluminium in ultra-light Mg-Li alloys shows considerably improved strengthening without a reduction in grain size. Increasing the lithium content causes in an increase of hardness.
