Upsetting of single materials such as aluminum, steel, copper and porous materials has been investigated many researchers in terms of friction, barreling effect and contact pressure distributions due to its relevance in metal forming. Also different shapes such as elliptical and polygonal shapes have been studied. In this paper, upsetting of composite or in other words bimetallic metals were studied experimentally. Cylindrical specimens consisting of two different materials were used in the experiments. Specimens were prepared as aluminum sleeve and copper core and upset at different reduction. This metal combination present a material model of which chemical composition is different.eninfo:eu-repo/semantics/closedAccessUpsettingBimaterialBarrellingCopperAluminiumRodsExtrusionDiesConference Object693696N/AWOS:000392260500174
