“…On the other hand, the behaviour of Au differs from that of Cu, which also belongs to Group 11 and has a VEC of 1. In the Pd-Cu-In ternary, Cu dissolves in the InPd 3 phase up to 26 at% (16 at% for Au), retaining the CuAu structure type (Ptashkina et al, 2015), but does not form the Cu 3 Au phase. Moreover, the analogous Pd 3 Sn phase, with the Cu 3 Au structure type, does not dissolve Cu at all; a ternary phase with a structure unrelated to fcc is formed instead (Kareva et al, 2014).…”

A new CuAu-type ternary phase (τ phase) is found in the AuPd-rich part of the Au-In-Pd system. It has a broad homogeneity range based on extensive (Pd,Au) and (In,Au) replacement, with the composition varying between AuInPd and AuInPd. The occupancies of the crystallographic positions were studied by single-crystal X-ray diffraction for three samples of different composition. The sites with m-3m symmetry are occupied by atoms with a smaller scattering power than the atoms located on 4/mmm sites. Two extreme structure models were refined. Within the first, the occupation type changes from (Au,In,Pd)(Pd,In) to (Au,Pd)(In,Pd,Au) with an increase in the Au gross content. For the second model, the occupation type (Au,In,Pd)(Pd,Au) remains essentially unchanged for all Au concentrations. Although the diffraction data do not allow the choice of one of these models, the latter model, where Au substitutes In on 4/mmm sites, seems to be preferable, since it agrees with the fact that the homogeneity range of the τ phase is inclined to the Au corner and provides the same occupation type for all the studied samples of different compositions.

Isothermal section of the Cu-In-Pd system at 800°C

Abstract: A combination of physicochemical analysis methods is used to study the phase equilibria in the Cu-In-Pd system. An isothermal section at 800°C has been constructed. The copper solubility in the binary phases of the In-Pd system is determined.
