Influência da taxa de deformação por laminação nas propriedades mecânicas na liga de alumínio 1100

Abstract

This work demonstrates how different strain rates of rolling influence the mechanical properties of the 1100 aluminum alloy. Experiments were carried out with specimens varying the deformation rate from 3.58 s-¹ to 16.1 s-¹ in cold rolling . The mechanical properties analyzed in this work were: hardness and ductility and limit of tensile strength. This work also demonstrates how the different rates of deformation influence the macrostructure of the aluminum alloy 1100. An increase of about 8% in the hardness of the alloy with different strain rates and a reduction of ductility from 20% to 50% was found.
