Ga-Ni (Gallium-Nickel) S.Y. Lee and P. Nash The assessed Ni-Ga diagram is based primarily on the data of [50Hel], [57Pea], and [79Fes]. Originally, six intermediate phases-b, d, g, g›, b›, and e-were reported by [50Hel]. a› and Ni3Ga4 were reported by [57Pea] and [69Ell], respectively. [50Hel] reported the maximum solubility of Ga in (Ni) to be about 28 at.% at 1211 C on the basis of powder X-ray measurements. However, detailed studies by [57Pea] with X-ray, thermal analysis, and metallography showed the maximum solubility to be 24.3 at.% Ga at 1212 C. [79Fes] confirmed the results of [ 57Pea] with microprobe analysis of samples annealed for 4 h to 1 month. No data on the solubility of Ni in (Ga) are available. 50Hel: E. Hellner, Z. Metallkd., 41, 480-484 (1950) in German. 57Pea: W.B. Pearson and D.M. Rimek, Can. J. Phys., 35(4), 1228-1234 (1957). 69Ell: M. Ellner, K.J. Best, H. Jacobi, and K. Schubert, J. Less-Common Met., 19, 294-296 (1969) in German. 79Fes: P. Feschotte and P. Eggimann, J. Less-Common Met., 63, 15-30 (1979) in French. Published in Phase Diagrams of Binary Nickel Alloys, 1991. Complete evaluation contains 5 figures, 4 tables, and 29 references. Special Points of the Ni-Ga System
