Lu-Th (Lutetium-Thorium) Editor The Lu-Th phase diagram is redrawn from [69Bad], except for the (Lu) cph phase field. [69Bad] showed a bcc to cph transformation in pure Lu at ~1370 C. Because pure Lu is now known to be cph up to the melting point under 1 atm pressure, the bcc to cph metastable transformation is shown to occur above the melting point of Lu in the present phase diagram.-H.O. 69Bad: T.A. Badayeva and P.I. Kuznetsova, Izv. Akad. Nauk SSSR, Met., (5), 156- 163 (1960) in Russian; TR: Russ. Metall., (5), 101-106 (1969). 1
