Abstract
Samples of bimetallic strip Cu-Al were cold rolled with different reduction
degrees, and the ones deformed with the highest reduction degrees were annealed afterwards at different temperatures for a period of one hour. The values of the hardness of the layers of the bimetallic strip were obtained as a function of the degree of deformation, and the annealing temperature. Global flow of curves hardness - total deformation, increases, where the increase in the hardness of aluminum with increasing degree of deformation is approximately linear. A decrease in hardness was observed with an increase in the annealing temperature, in both the aluminum layer and the copper layer.
