Cast Magnesium

The potential of cast magnesium alloys for being used as structural materials in lightweight applications is assessed. The ability of the alloys for mechanical performance is evaluated and compared against the ability of widely used structural aircraft cast aluminum alloys. The specific quality index QDS, devised for evaluating both cast and wrought aluminum alloys, will be exploited to evaluate the ability of a number of cast magnesium alloys for mechanical performance. The exploited quality index QDS involves the material’s yield strength Rp to account for strength, the strain energy density W to account for both tensile ductility and toughness, and the material’s density ρ. The effects of differences in chemical composition and heat treatment conditions on the mechanical performance of cast magnesium alloys have been assessed. The use of the quality index QDS has been proved to appreciably facilitate the evaluation of the mechanical performance of cast magnesium alloys and also the comparison between alloys of different base materials. The results quantify the gap to be closed such as to involve cast magnesium alloys in aircraft structural applications.

AbstractA growing interest in wrought magnesium alloys has been noticed recently, mainly due to development of various SPD (severe plastic deformation) methods that enable significant refinement of the microstructure and – as a result – improvement of various functional properties of products. However, forming as-cast magnesium alloys with the increased aluminum content at room temperature is almost impossible. Therefore, application of heat treatment before forming or forming at elevated temperature is recommended for these alloys. The paper presents the influence of selected heat treatment conditions on the microstructure and the mechanical properties of the as-cast AZ91 alloy. Deformation behaviour of the as-cast AZ61 alloy at elevated temperatures was analysed as well. The microstructure analysis was performed by means of both light microscopy and SEM. The latter one was used also for fracture analysis. Moreover, the effect of chemical composition modification by lithium addition on the microstructure of the AZ31-based alloy is presented. The test results can be helpful in preparation of the magnesium-aluminum alloys for further processing by means of SPD methods.

This paper reviews the outcome of bismuth and antimony trappings on the microstructure and mechanical behavior of an assortment of commercial magnesium alloys. Various compositions of the Bi and Sb were discussed along with/without combination of other alloying elements. These additions have revealed to be resulted in the formation of Mg3Bi2 , Mg3Sb2 intermediate phases when added upon with corresponding alloying elements. Moreover the reasons for the observed changes due to the addition of these alloying elements were also reviewed. It is found that the accumulation of Bi phase as well as intermetallics and Sb intermediates has greatly improved the microstructure belonging to the as cast magnesium alloys thereby improving both mechanical and thermo-mechanical properties. It is also observed in the review that addition of thesealloying elements acted as grain refiner and improved the corrosion resistance of commercial magnesium alloys.
