Kyrdyumov Institute for Metall Physics of N.A.S. of Ukraine popup.description2 An effective alloying system for providing improved mechanical and technological properties of model cast Al-Cu alloys (Al-4.6%Cu-0.4%Mn-0.2%Ti), using magnetohydrodynamic melt mixing was choosen. It was shown that the most effective alloying element which improved the strength characteristics of the alloy was Sn. The introduction of 0.1-0.2% Sn followed by heat treatment led to the 50% increase in the yield strength, 15% - in the tensile strength in the absence of Sc, Zr and with low content of Mn in the alloy. Sn modified the kinetics of the decomposition, providing high density of precipitate and slow coalescence of nano-sized particles of the strengthening phase, which resulted in higher strength characteristics of the alloy.
