A novel continuous squeeze casting-extrusion process for grain refinement and property improvement in AZ31 alloy

Abstract A novel continuous squeeze casting-extrusion (CSCE) process was proposed to prepare high strength and toughness AZ31 alloy. The average grain size of AZ31 alloy after CSCE was reduced to 2.43 μm. An excellent combination of the ultimate tensile strength of 321 MPa and the elongation of 14.7% was achieved.
