Notes:
Effects of extrusion on mechanical properties and damping capacity of Mg-1.8wt.%Cu-0.5wt.%Mn (MCM1805) alloy have been investigated. Tensile tests and dynamic mechanicalanalyzer were respectively used to measure tensile properties and damping capacity at roomtemperature of as-cast and as-extruded MCM1805 alloy. The microstructure was studied using opticalmicroscope, X-ray diffraction and scanning electron microscope with an energy dispersive X-rayspectrometer. Granato-Lücke model was used to explain the influences of extrusion on dampingcapacity of MCM1805 alloy. The results showed that extrusion dramatically decreases the grain sizebut has little influence on phase composition and solute atoms concentration of MCM1805 alloy, andthe grain refinement was the dominant reason for the obvious increase of tensile properties anddecrease of internal friction of MCM1805 alloy
