Hf-Mg (Hafnium-Magnesium) A.A. Nayeb-Hashemi and J.B. Clark Because the equilibrium phase diagram of Mg-Hf has not been experimentally determined, the probable diagram is represented schematically. According to an early investigation by [49Sau], Hf did not alloy with Mg after prolonged exposure to liquid Mg at high temperatures (~1000 C). [60Tho] noted that there may be considerable liquid solubility based on the analogy to titanium and zirconium. This does not appear to be true, because Mg boils at ~1100 C and Hf melts at 2231 C. 49Sau: F. Sauerwald, Z. Anorg. Chem., 258, 296-300 (1949) in German. 60Tho: D.E. Thomas and E.T. Hayes, The Metallurgy of Hafnium, U.S. Government Printing Office, Washington, DC, 202 (1960). Published in Phase Diagrams of Binary Magnesium Alloys, 1988.
