Originální abstrakt
Aluminium alloys have a very low density, excellent oxidation resistance and workability. However, their usability is often limited by poor mechanical resistance compared to other metals. Several methods to enhance mechanical properties of aluminium are known. One of them is a composite alloy formation, where a second phase with high elastic modulus is added. In a case of aluminium strengthened by intermetallics, the eutectic reaction can be properly utilized. Based on a constituent concentration, the hypo-eutectic or hyper-eutectic alloys could be produced. The paper focuses on the results of microstructural and differential thermal analyses of hypereutectic alloys, which were produced by an unconventional method consisting of sacrificial nickel coating formation on aluminium substrate and its subsequent annealing at the temperature above the melting point of aluminium.
