Adrian and Choroszyński, M.}, number={No 2}, journal={Archives of Foundry Engineering}, howpublished={online}, year={2013}, publisher={The Katowice Branch of the Polish Academy of Sciences}, abstract={The high mechanical properties of the Al-Li-X alloys contribute to their increasingly broad application in aeronautics, as an alternative forthe aluminium alloys, which have been used so far. The aluminium-lithium alloys have a lower specific gravity, a higher nucleation andcrack spread resistance, a higher Young’s module and they characterize in a high crack resistance at lower temperatures. The aim of theresearch planned in this work was to design an aluminium alloy with a content of lithium and other alloy elements. The research includedthe creation of a laboratorial melt, the microstructure analysis with the use of light microscopy, the application of X-ray methods to identify the phases existing in the alloy, and the microhardness test.}, type={Artykuły / Articles}, title={Structure and Mechanical Properties of Al-Li Alloys as Cast}, URL={http://journals.pan.pl/Content/87333/PDF/01_paper.pdf}, doi={10.2478/afe-2013-0027}, keywords={Al-Li alloys, Aerospace industry, precipitation hardening}, }
