| 中文摘要 | die cast az91-xymm (x = 0-0.8 wt.%) magnesium alloys with excellent tensile properties and corrosion resistance behavior were successfully prepared by a simple addition of yttrium-rich misch metal (ymm) to az91. influences of ymm on the microstructure, mechanical properties and corrosion behavior of az91 were investigated. the results showed that addition of ymm to die cast az91 alloy could re. ne the microstructure including primary alpha-mg and eutectic beta-mg17al12. when the content of ymm reached 0.8 wt.% a small quantity of al2y phase would form. the tensile properties were improved greatly with addition of ymm to az91. the creep rate of the az91-ymm alloys, tested at 150 degrees c/50mpa, was one order of magnitude lower than that of az91. when addition of ymm was more than 0.3 wt.%, the salt-spray corrosion resistance of az91-ymm alloys could be 30-40 times of that of az91. the improvement of corrosion resistance with addition of ymm was confirmed by the results of electrochemical polarization experiments. mechanism of the improvement of mechanical properties and corrosion behavior caused by ymm was also discussed. |
