Ni-Zn (Nickel-Zinc) P. Nash and Y.Y. Pan The assessed Ni-Zn phase diagram is essentially in agreement with the previous evaluation of [Hansen]. The boundary of the (Ni) phase is based on the work of [38Sch] and [74Bud]. According to the suggestion of [79Mor], the g and g1 phase regions have been combined to give a single g phase region. In the high- Ni side of the g phase region, there is an inversion anti-phase domain (IAPD) structure. The maximum solubility of Ni in (Zn) is very small. The magnetic transformation extends from 354.2 C at pure Ni [82Rhy] to room temperature at about 17.4 at.% Zn. By metallographic and X-ray examination, [72Lia] observed the transformation from the CsCl-type cubic b phase to the AuCu-type fct b1 phase. The alloys, quenched in a liquid nitrogen or water bath, showed a martensitic-type transformation. [84Mur] studied this transformation with optical and electron microscopy in a Ni50Zn50 alloy and found this transformation to be martensitic in the case of quenching and massive in the case of slow cooling. 38Sch: J.
