Summary:The article examines the impact of changes in homogenization temperature in the hardening process on the microstructure of aluminum alloys. Samples where the research was conducted were cast from AlSi10CuNiMn alloy produced by gravity casting technology in metal mold. Subsequently, the castings were subjected to a heat treatment. In an experiment with changing temperature and staying time in the process of homogenization. The microstructure of the alloy was investigated by methods of light and electron microscopy. Examination of the microstructure has focused on changing the morphology of separated particles of eutectic silicon and intermetallic phases. Analysis of intermetallic phases was supplemented by an analysis of the chemical composition - EDS analysis. Effect of heat treatment on the properties investigated alloy was further complemented by Vickers microhardness. Investigated alloy is the result of longtime research conducted at Faculty of Production Technology and Management.
