摘要：

The experimental heat resistant alloy Al-3.3Cu-2.5Mn-0.5Zr (wt. %) has been manufactured using the method of electromagnetic casting (EMC) providing solidification at an ultra-high rate (-104 degrees C/s). The microstructure, phase composition, mechanical and electrical properties of the alloy in as-cast state and after cold rolling followed by annealing has been extensively studied using both thermodynamic calculations and experimental analysis. The microstructure of the as-cast EMC rod consists of the fine Al2Cu phase inclusions and aluminum matrix where all Mn and Zr and most of Cu are dissolved. The annealing of cold rolled strip at 400 degrees C allows reaching the optimal combination of strength, electrical conductivity and thermal stability.
