Влияние дополнительного легирования скандием и скандием с цирконием на прочностные свойства сплавов системы Al-Mg 2 Si

The effect of Sc and Sc + Zr on the structure and properties of Al-Mg-Si alloys is studied using measurements of hardness, electrical resistivity, mechanical properties, light and electron microscopy analysis. Alloying of Al-Mg 2 Si alloys with transition metals (Sc or Sc + Zr) results in their strengthening upon natural ageing and has no effect in the case of artificial ageing. The observed effects are explained using electron microscopy and local X-ray analysis.
