For determining of the dependence between cooling Speer, chemical composition and structure of the Al-Si-Cu aluminium cast alloy the thermo-analysis was carried out, using the UMSA device (Universal Metallurgical Simulator and Analyzer), next the optical and electron scanning microscopy was used for investigation of the structure, phase and chemical composition of the AC-AlSi7Cu3Mg grade Al cast alloy also using the EDS microanalysis as well the EBSD technique.
