Microstructure and mechanical properties of gadolinium-and misch metal-added Mg-Al alloy
文献摘要:
The study investigates the effects of individual and combined additions of gadolinium(Gd)and misch metal(MM)on the microstructure and mechanical prop-erties of Mg-4Al and Mg-9Al alloys.The results show that the additions significantly alter the microstructure and grain size of the base alloys.Mg-4Al based alloys have globular morphology,whereas Mg-9Al based alloys have dendritic morphology.The addition of alloying elements,Gd and MM,introduces rectangular-shaped Al2Gd phase and needle-shaped Al11RE3 phase,respectively.The best mechanical properties at room temperature are shown by Mg-9Al-2Gd alloy with tensile strength and elongation of 214 MPa and 6.0%,respectively,whereas Mg-4Al-2Gd alloy exhibits the best properties at elevated temperature(150℃)with tensile strength and elongation of 172 MPa and 14.0%,respectively.The study also reports the microhardness value of different phases along with the cast alloys.Eutectic Mg17Al12 phase shows the highest hard-ness(VHN 92)followed by lamellar Mg17Al12(VHN 83)and α-Mg matrix(VHN 68).
