Аннотация: Today aluminum alloys are widely used in the industry. Therefore, improving the quality of castings from aluminum alloys is one of the essential tasks in the field of foundry. This is achieved by the development of new alloy compositions, their modification, refining, and heat treatment. The purpose of this research was to study the effect of processes occurring at the eutectic transformation temperature range on the formation of the structure of the aluminummini-copper alloy. The influence of processes developing in the temperature range 5-7°C above the onset of eutectic transformation temperatures on the formation of the alloy structure was studied. The research showed that the microstructure of the eutectic aluminum-copper alloy is divided into separate components with their subsequent combination (α-solid solution and CuAl2 phases). Based on the study on Al-33% Cu and Al-12% Si alloys, it can be stated that being slightly overheated, microstructures with dispersed phases are formed at the eutectic equilibrium temperature range, both in the eutectic components and secondary phases. © 2006-2020 Asian Research Publishing Network (ARPN).
