Abstract
Abstract Compression tests were performed in order to observe and investigate the rheological behavior of wrought aluminum alloy while varying the processing parameters such as liquid fraction, strain rate. The results of an experimental investigation using Al 6061 with a closed die are presented here. Specimens of wrought aluminum alloy were characterized with their rheological behavior during partial melting and holding in the semi-solid state. The characteristics of flow between solid and liquid phases by considering liquid segregation are examined by restricting material (100% of packing rate in a closed die) during compression. Also, the strain–stress curves and microstructures of the rheological materials were investigated. Moreover, the tests allow the apparent viscosity of the alloys to be determined as a function of the liquid fraction and shear rate together with the densification behavior of the solid phase. Finally, the experimental results should be used in flow and solidification analyses and useful for manufacturing good SSM products through observing the microstructures according to changes of the solid fraction and compression rate.
