Tensile behavior of multiple forged 6082 Al alloy

Abstract

The present study focus on the influence of multiple forging (MF) on the tensile behavior of 6082 aluminium alloy, where the MF specimens were achieved using multi-step closed die forging. Cylindrical tensile specimens were machined from the MF specimens then subjected to tensile testing. Beside the main target of the study, the effect of MF on microstructure homogeneity and the fracture surface of the samples were studied using hardness testing, optical and scanning electron microscopy respectively.

The results show the influence of MF on the tensile strength and the maximum elongation; with increasing passes of MF the strength increases while the maximum elongation decreases. The hardness measurement results demonstrate the structure homogeneity, the fractography pictures show ductile fracture of the specimen, and the micrographs describe the microstructure development during MF process.
