摘要

Mg_(97)Y_2Cu_1 (at. percent) cast alloy has an 18R-type long period ordered (LPO) structure that forms coherently with the alpha-Mg matrix during casting. Hot working improved the mechanical properties of the LPO Mg_(97)Y_2Cu_1 cast alloy. Hot-extruded LPO Mg_(97)Y_2-Cu_1 alloy exhibited high tensile mechanical properties. The yield strength, tensile strength and elongation were 297 MPa, 377 MPa and 8.1 percent, respectively, at ambient temperature, and 273 MPa, 344 MPa and 16.3 percent, respectively, at 473 K.
