Abstract

The Er-Mg system was examined using differential thermal analysis (DTA), X-ray examination, metallography, and microprobe analysis. Four intermediate phases are found to exist, and their crystal structures have been confirmed or determined as the following:β phase (≈Er2Mg) (cubic, cI2-W type, peritectic formation 1255 °C); ErMg (cubic, cP2-CsCl type, peritectic formation 830 °C); ErMg2 (hexagonal, hP12-MgZn2 type, peritectic formation 670 °C); and Er5Mg24 (cubic, cI58-α-Mn type, peritectic formation 600 °C). Theβ phase undergoes a eutectoidal decomposition at 680 °C and 30.5 at. pct Mg. A eutectic reaction was observed to occur at 570 °C and 89.5 at. pct Mg. Comparisons of the general properties between the ErMg phases and with those of the other R-Mg compounds (R = rare earth) are briefly discussed. Properties and structures of the R-Mg, R-rich alloys are specially considered and compared with those of a few groups of rare-earth alloys. The alloying behavior of R-rich R-Me alloys (R = Ho, Er, Tm, Lu; Me = Mg, Cd, In, Tl) is systematically presented and/or predicted.
