摘要：

This study demonstrated the effect of solid fraction and forging pressure on mechanical properties of the product of wrought aluminum alloys fabricated by the indirect rheoforging through electromagnetic stirring (EMS). In addition to EMS, the rheological material was examined for its response to various pouring temperatures as the rheo-material was forged into a sample which consisted parts that were directly and indirectly subjected to forge pressure. As results of investigating the relationship between microstructural features and mechanical properties of the product through microscopic inspection, the EMS rheo-forged materials revealed a fine and globular microstructure. Microstructures of Al6061 wrought aluminum alloy with uniform solid and liquid phase distributions (no segregation) demonstrated good mechanical properties with tensile strengths of up to 341 MPa.
