Al-Tm (Aluminum-Thulium) Editor The Al-Tm phase diagram was drawn by [Moffatt] based on the similarity to other Al-Rare Earth systems (except for divalent Eu and Yb) [67Bus]. [63Jon] reported a eutectic at 645 с 3 C and 1.7 с 2 at.% Tm between (Al) and Al3Tm. The Al3Tm phase has the cubic AuCu3-type structure. A second intermetallic phase with a cubic structure is presumed to be Al2Tm. Some structural data for the orthorhombic AlEr-type AlTm phase have been reported by [67Bec].-H.O. 63Jon: T.I. Jones, L.R. Norlock, and R.R. Boucher, J. Less-Common Met., 5, 128 (1963). 67Bec: C. B‚cle and T. Lemaire, Acta Crystallogr., 18, 840 (1967). 67Bus: K.H.J. Buschow and J.H.N. van Vucht, Philips Res. Rep., 22, 233-245 ( 1967). This updates the evaluation by K.A. Gschneidner, Jr. and F.W. Calderwood published in Bull. Alloy Phase Diagrams, 10(1), Feb 1989, which contains 1 table and 11 references. 1
