Abstract

This study was conducted on AA 5052 sheets that had been produced by direct casting and AA 5050C sheets that had been produced by twin roll casting to microstructurally and mechanically characterize these alloys and evaluate their dynamic aging occurrence as a function of the strain rate applied in uniaxial tensile tests. In general, AA 5052 alloy showed higher strength values and lower ductility. Analysis of the aspect of tensile curves showed serrations in both alloys, indicating rapid and successive stresses variations in the plastic deformation region for both alloys, suggesting dynamic aging occurrence and how this effect is more pronounced at lower displacement speed. The frequency and magnitude of the decrease stress can be associated with the distinct Mg content of the alloys, being smaller in the AA 5050C.
