Sažetak
Determination of solidification sequence of Al- 2, 5wt.%Mg-0, 7wt.%Li alloy represents a challenge due to the strong influence of chemical composition, grain structure and thermodynamic parameters on the phase precipitation and transformation. Modelling of equilibrium phase diagrams in correlation with simultaneous thermal analysis, X-ray diffraction and metallographic investigations enables determination of solidification sequence. Besides commonly precipitated intermetallic phases, expected in the alloy containing >2, 0wt%Mg, stabile δ (AlLi) phase was also found. These phases nucleated at the αAl grain boundaries and grow at the expense of previously precipitated metastable δ’ (Al3Li) causing the formation of precipitation free zones.
