Mg-Ni (Magnesium-Nickel) A.A. Nayeb-Hashemi and J.B. Clark The assessed Mg-Ni phase diagram in the composition range 0 to 34 at.% Ni has been taken from [34Hau]; the Ni-rich region of 80 to 100 at.% Ni from [08Vos]; and the MgNi2 liquidus basically from thermodynamic modeling, incorporating some of the data of [08Vos], [34Hau], and [78Bag]. Agreement with the assessed boundaries is quite satisfactory and is also consistent thermodynamically with the experimental data. [80Som] reported the formation of metallic glasses in Mg-Ni alloys in the composition range 8 to 25 at.% Ni. The alloys were rapidly quenched from the liquid state. The composition range of complete glass formation was 10 to 18 at.% Ni. [80Som] also noted that the transformation of the glassy Mg-Ni alloys to a stable crystal structure occurred via a metastable intermediate phase. [08Vos] reported that Ni and MgNi2 are ferromagnetic below 340 and 235 C, respectively. The reported Curie temperature for Ni is in fair agreement with 360 and 358 C given in [35Aro] and [51Boz], but later investigators [60Wol, 75Bus] disputed the ferromagnetic behavior of MgNi2. 08Vos: G.
