UVOD / INTRODUCTION:
With the growing energy crisis and difficulties in obtaining new metals, layered composites are becoming more widely used, with aluminiumcopper bimetal playing the dominant role. It is characterised by high electrical and thermal conductivity, high corrosion resistance, and relatively low density. The production costs of bimetal using rolling technology are low, and its use in a technical solution allows 30% to 50% savings compared to monolithic copper. The composite is used in radiators, cables, cooling fins, heat exchangers, and other electronic and electrical components. However, the number of applications of Al/Cu bimetal is limited by the quite significant effect of heat on its elastic-plastic properties and structure. The purpose of the research conducted was to determine the effect of heat through growth and short-term withstanding of Al/Cu bimetal in the temperature range of up to 250 – 500 °C on its springback effect and the beginning of plasticity in its extreme layers under bending conditions.
