The main goal of the research presented in this paper is to gain a deeper understanding of solidification processes in terms of porosity formation in AlSi7Cu0.5Mg alloy through complex data evaluation obtained from thermal analysis, simulation software ProCAST and also from real melts. Formation of porosity (micro, macro porosity) was examined under different casting conditions, the pouring temperature varied from 730 °C to 650 °C. The experiment will attempt to analyze, how the pouring temperature effects the formation and character of porosity. For this purpose was various methods were used, not only real castings evaluation, but also advanced porosity module integrated into simulation software ProCAST. Experiments also try to compare simulation results with real conditions, to determine software abilities and accuracy. Specific casting and mold were designed to be able to observe porosity formation.

Keywords: simulation, thermal analysis, porosity, aluminum alloys
