The rheoforming of Al7075 using the electromagnetic stirring (EMS) approach is demonstrated. The mechanical properties, chemical composition, and microstructural observations are performed on the produced samples. The rheo-slurry produced by EMS of a 60 A stirring current was forged for 20 s at temperatures of 625 °C (solid fraction, fs = 35 per cent) and 615 °C (fs = 50 per cent) under applied pressures of 170, 200, 220, and 250 MPa. The highest tensile strength of 404 MPa was recorded for a sample produced at a temperature of 615 °C and a pressure of 220 MPa that underwent a T6 heat treatment. The sample produced at 625 °C achieved its highest tensile strength for an applied pressure of 200 MPa and a T6 heat treatment. The improvement in the ductility observed in these samples is a result of the removal of a liquid phase that contains Cu and Si from the boundaries between grains of the pure α phase material. The elongation properties of the sample were investigated and correlated with the observed microstructures.
