Analyses of impurities in cast magnesium-rare earth elements alloys

100%

Braszczyńska-Malik K. N. , Żydek A. , Polis A.

tom Vol. 8, iss. 4

19-22

Microstructure analyses of impurities in binary Mg-3%RE and Mg-8%RE alloys are presented. Light microscopy and scanning electron microscopy (SEM+EDX) techniques were used to characterize the investigated material. In microstructure, besides [alpha]-Mg solution and [alpha]+Mg12RE eutectic, some intermetallic compounds with different morphology (needle-like, square-like) were observed. X-ray phase analyses showed that intermetallic compounds were RE3Si2 and RE2Fe14Si3. Their location in axis of primary [alpha]-Mg dendrites suggests that some parts of them may act as heterogeneous nucleation sits for magnesium.
