- Abstract
The 450 °C isothermal section of the Ni-Sb-Zn ternary system with an emphasis on the Zn-rich corner was experimentally determined by means of optical microscopy, SEM-EDS analysis and x-ray diffraction. The existence of two true ternary phase, the NiSbZn (τ) and NiSbZn (τ) phase, was confirmed in the system at 450 °C. NiSbZn (τ) had an MgAgAs-type structure with a lattice parameter a = 0.58971 nm. NiSbZn (τ) is a ternary compound found in this system for the first time whose composition range spanned from 35.5-38.0 at.% Ni, 17.3-26.3 at.% Sb, 36.9-45.2 at.% Zn. It should be noted that the phase relationships at 450 °C are significantly different from the previous reported ones at 600 and 297 °C. The solubilities of Ni in SbZn, SbZn and SbZn were limited. The maximum solubilities of Sb in δ-NiZn, γ-NiZn and β-NiZn were 0.1, 4.0 and 1.5 at.%, respectively and the maximum solubilities of Zn in NiSb and NiSb were 5.6 and 1.6 at.%, respectively.
