| Popis: |
Crystalline Mg-Cu-Y alloy system was fabricated using the squeeze casting technique. Microstructure showed the multiphase structure composed of primary Mg rich phase distributed among the lamellae patterns, alternative layers of LPSO Mg phase and intermetallic phases. High microhardness and tensile strength of 104 HV and 223 MPa respectively were observed in the squeeze cast alloy. A good combination of compressive strength (706 MPa) and ductility (19%) was also achieved in the crystalline alloy which is unlikely to be attainable in amorphous Mg-Cu-Y system. The formation of LPSO phase in the current Mg-Cu-Y alloy mainly contributed to the high mechanical properties. |
