Microstructure change of the metals and alloys as a result of variable crystallisation conditions also by mind of cooling rate change influence the mechanical properties. In this work there are presented the interdependences between the cooling rate, chemical composition and microstructure of the cast aluminium alloy Al–Si–Cu as a result of the thermo-derivative analysis, using the UMSA (Universal Metallurgical Simulator and Analyzer) device. An important tool for the microstructure evaluation of the Al type AC-AlSi7Cu3Mg alloy was the light and electron scanning microscopy technique.
