Abstract
Two homeotypical phases occur at the mole fraction x(Al)approximate to 0.75 in the ternary system Co-Ni-Al: the pseudoternary intermetallic compound (Co,Ni)(4)Al-13(h) (space group C2/m, Pearson code mC(34-1.8)) [Notation, according to Parthe et nl. (1993). TYPIX, Standardized Data nod Crystal Chemical Characterization of Inorganic Structure Types (Springer, Berlin), Vol. 2, p. 269, Vol. 3, p. 1055]. For structures with partly occupied sites, the hybrid Pearson code is given as (the sum of the multiplicities of all, fully or partly occupied sites in the unit cell)-(number of structural vacancies in the unit cell)], and the ternary compound Co2NiAl9 (Immm, oI96). Powder diffraction data are reported for these materials or phases-from the viewpoint of phase equilibria-immediately neighboring phases. (C) 1999 International Centre for Diffraction Data.
