QIU Cai'an;JIN Zhanpeng;HUANG Peiyun Central South University of Technology; Changsha. ISOTHERMAL SECTION OF THE W-Ni-Cu SYSTEM AT 1017℃. Acta Metall Sin, 1988, 24(5): 403-406.
Abstract The isothermal section of the W-Ni-Cu ternary system at 1017℃ wasdetermined by means of diffusion couple sepecimens, EMPA and X-ray diffrac-tion. Body-centered tetragonal Ni_4W and orthorhombic NiW but NiW_2 observedin the W-Ni binary system at this temperature. The solubility ranges of W andCu in Ni_4W are 16.95--20.51 at-% and 0--4.36 at-%, respectively. The maximumsolubility of W in γ(Ni) is 13.11 at-%
