during casting. Hot working improved the mechanical properties of the LPO Mg97Y2CU1 cast alloy. Hot-extruded LPO Mg97Y2-Cu-1 alloy exhibited high tensile mechanical properties. The yield strength, tensile strength and elongation were 297 MPa, 377 MPa and 8.1%, respectively, at ambient temperature, and 273 MPa, 344 MPa and 16.3%, respectively, at 473 K.
