Abstract: The present invention relates to a method of semi-solid indirect squeeze casting for Mg-based composite material, which aims at improving the mechanical property of the cast by adding magnesium zinc yttrium quasicrystal of high hardness, high elastic modulus and excellent matrix binding property acting as the reinforcement into the magnesium alloy matrix and manufacturing the cast through smelting using a vacuum atmosphere smelting furnace, agitating with ultrasonic wave assisted vibration in the rotating impeller jet agitation furnace and indirect squeeze casting against the problem of poor wettability, easy agglomeration, inhomogeneous distribution between the reinforcement particles and the matrix materials and poor properties of the manufactured cast. The manufacturing method of the present invention has advanced technologies and detailed and accurate data.
