“…In contrary, the clear kinks in the enthalpy curves for (Sn-Zn) + Ni alloys along the cross sections C ( x Sn / x Zn = 9:1) and D ( x Sn / x Zn ≈ 4:1) shown in Fig. 4 and 5 indicate formation of a solid phase and denote the liquidus limit at 873 K. The corresponding points are in reasonable agreement with the estimated liquidus line at 873 K given by Yuan et al[ 37 ] which is shown as a dashed line in Fig. 1 .…”

The partial and integral enthalpies of mixing of liquid ternary Ni-Sn-Zn alloys were determined. The system was investigated along two sections xNi/xSn ≈ 1:9, xNi/xSn ≈ 1:6 at 1073 K and along two sections xSn/xZn ≈ 9:1, xSn/xZn ≈ 4:1 at 873 K. The integral enthalpy of mixing at each temperature is described using the Redlich-Kister-Muggianu model for substitutional ternary solutions. In addition, the experimental results were compared with data calculated according to the Toop extrapolation model. The minimum integral enthalpy of approx. −20000 J mol-1 corresponds to the minimum in the constituent binary Ni-Sn system, the maximum of approx. 3000 J mol-1 is equal to the maximum in the binary Sn-Zn system.

“…Liang et al (2011) also mention the existence of a ternary phase with similar composition at 773 K. According to their interpretation this is a stabilization of an incommensurate Ni 3 Sn 2 low-temperature phase to higher temperatures. In the light of the present results, however, it is likely to be Ni 5À Sn 4 Zn ( $ 0.25) just as at 973 K. Yuan et al (2011) also report the existence of a ternary phase with a similar composition at 873 K. The stability range of the Ni 5À Sn 4 Zn ( $ 0.25) compound is therefore the subject of ongoing investigations (Rajamohan et al, 2012). In both structures, the Ni sublattice is not fully occupied, since in Ni 5À Sn 4 Zn ( $ 0.25) the Ni2 position has an occupancy significantly below 1.…”

Work on the ternary Ni-Sn-Zn phase diagram revealed the existence of the title compound pentanickel tetratin zinc, Ni(3.17)Sn(2.67)Zn(0.67) [Schmetterer et al. (2012). Intermetallics, doi:10.1016/j.intermet.2011.05.025]. It crystallizes in the Ni(5)Ga(3)Ge(2) structure type (orthorhombic, Cmcm) and is related to the InNi(2) type (hexagonal, P6(3)/mmc) of the neighbouring Ni(3)Sn(2) high-temperature (HT) phase, but is not a superstructure. The crystal structure was determined using single-crystal X-ray diffraction. Its homogeneity range was characterized using electron microprobe analysis. Phase analysis at various temperatures indicated that the phase decomposes between 1073 and 1173 K, where a more extended ternary solid solution of the Ni(3)Sn(2) HT phase was found instead.
