Deformation behavior of the AlMg4.5Cu0.5 type alloy sheet

Abstract

Deformation behavior of the AlMg4.5Cu0.5 type alloy sheets was examined after cold rolling and annealing in the range of temperature from 220°C to 520°C, water quenching and natural aging. The low temperature annealed samples, characterized by fine grained recrystallized structure and high content of Cu-Mg precipitates, have shown a superior hardening ability in uniaxial tension and formability in biaxial stretching. The natural aging didn't bring any important changes of the properties in respect to the as-quenched condition of the tested material
