of as-cast 7075 alloy, and the optical addition of Al2O3p is 2 wt%. The primary α-Al becomes uniform and orderly, and the Mg(Zn,Cu,Al)2, Al7Cu2Fe phases are refined. After hot extrusion, the Mg(Zn,Cu,Al)2...), and transmission electron microscopy (TEM). The experimental consequences reveal that the optimal addition of Al2O3p was 2 wt%. After hot extrusion, the Mg(Zn,Cu,Al)2 phases partially dissolve into the matrix......
