Isothermal Sections of Pd-Cu-Sn System at 500 and 800 °C

New Structure and Insight on the Phase Transition within the Cu-Pd-Sn System with 25 at. % Sn

“…The characteristic Bragg peaks of the LT phase, marked with diamonds, were indexed in agreement with an orthorhombic unit cell with space group 𝑃 𝑛𝑚𝑎 and lattice parameters as listed in Table 1 . This is similar to the reported structure of the related compound Cu 25 Pd 50 Sn 25 reported by [31] , also listed in Table 1 . The volumes of the unit cells differ by less than 0.1% despite the difference in composition.…”

“…The orthorhombic structure in [31] was interpreted as a HT phase since the investigated samples were quenched from high temperatures. However, with the insight from the present study, it is clear that they correspond to the orthorhombic LT structure.…”

“…More recently, isothermal sections of the Cu-Pd-Sn system at 773 and 1073 K have been described by Kareva et al [31] . The data was based on numerous specimens annealed at 773 and 1073 K, quenched, and characterized at room temperature.…”

Synthesis and crystal structure of a new Cu3Au-type ternary phase in the Au–In–Pd system: distribution of atoms over crystallographic positions

“…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). So, the VEC definitely cannot be the only factor determining the crystal structure of Pd-based intermetallics.…”

Critical evaluation and thermodynamic modeling of the Pd–Sn system

“…The prototype could be either NiAs or Ni2In. Based on ternary phase diagram measurements [14,24,25], most probably γ_Pd2Sn is of Ni2In type. However, the Ni2In structure still broadly belongs to the NiAs family, phases of Ni2In and NiAs type can form continuous solid solution in ternary system [25].…”
