Rheocasting of Al-Cu alloy A201 with different silver content. 10th International Conference on Semi-Solid processing of alloys and composites (S2P). Aachen, Germany and Liege, Belgium, 16 - 18 September, pp 18http://hdl.handle.net/10204/324010th International Conference on Semi-Solid processing of alloys and composites (S2P). Aachen, Germany and Liege, Belgium, 16 - 18 September 2008Rheocasting of alloys A206 and A201 was investigated in this study. Conical bars with different silver contents were produced using CSIR rheoprocess technology, together with high pressure die casting. The results showed that addition of Ag to alloy A206 increased the mechanical properties of the alloy. However, the addition of Ag also resulted in Cu-rich phases to precipitate at the grain boundaries of the as-cast material. The solution treatment used in this study was unable to dissolve all of this phase, especially in the 1.12%Ag-containing alloy. This resulted in slightly decreased mechanical properties compared to the 0.63%Ag-containing alloy. The T6 mechanical properties (strength and elongation) obtained in this study for rheocast A206 and A201 are better than those reported for permanent mould castings of alloy A206 and A201enCSIR-RheoprocessAl-Cu alloy A201SilverSemi-solid processingAlloysCompositesConference PresentationMasuku, E., Moller, H., Govender, G., & Ivanchev, L.
