Reciprocating extrusion is a novel method to refine the grains and inclusions of 7075 Al alloy. The reciprocatingly extruded 7075‐T6 alloys exhibit superior strength‐toughness combinations to conventional 7000 series alloys. Their available yield strength used in unstable crack growth condition can reach up to 550 MPa. The improved mechanisms in microstructure and properties are discussed.
