“…1. The XRD pattern corresponding to sample S4-500 can be related to the phase A reported by Elding-Pontén et al [15] XRD patterns corresponding to S2-500 and S3-500 samples exhibit several peaks related to both δ and A phases. The intensity of peaks related to phase δ diminishes with In content while the intensity of those related to phase A increases (see enlarged region displayed in Fig.…”

“…These phases would transform one to another with the continuous rotation of the sub-motif in the electron diffraction pattern. The phase A′ reported by Jain et al [9] have not been detected by Elding-Pontén et al [15] and it would be incorporated in the A phase.…”

“…Some X-ray diffraction (XRD) data for phases η and η′ were reported by Bolcavage [11] although they seemed inconsistent. On the other hand, Elding-Pontén et al [15] proposed that the η þη′ field is composed of three distinct phases, namely A at high temperatures and B and C at low temperatures. These author described phase A and B as a 10a Â 10b Â 1c supercell of the hexagonal cell related to phase h whereas phase C was described with an orthorhombic cell.…”

“…In general, all these phases can be described as NiAs-Ni 2 In-type superstructures [8,15,16]. The principal reflections of the related diffraction patterns can be indexed with an hexagonal cell, whereas the remaining reflections present low intensity and are related to domain twining [15,16]. Accordingly, the accurate identification of crystal structure is very difficult.…”

“…The compositional homogeneity ranges of the high temperature g¢-Cu 6 Sn 5 and Cu 2 In phases in the binary systems are 54.5-56.5 at.% Cu 15,16 and 64-67 at.% Cu, 17,18 respectively. Despite the differences in compositional homogeneity ranges, both of the two phases have the B8 1 /B8 2 (NiAs/Ni 2 In) crystal structures 19,20 and could potentially form a continuous solid solution. The continuous compositional distribution as shown in Fig.…”

Sn-In alloys are promising low-melting-point Pb-free solders. Knowledge of the ternary Sn-In-Cu liquidus projection is important for Sn-In solder applications. Sn-In-Cu ternary alloys were prepared and their primary solidification phases and phase-transformation temperatures during heating were determined. The liquidus projection of the Sn-In-Cu ternary system was determined based on the primary solidification phase at different compositional regimes, the phase-transformation temperatures of the ternary alloys, the phase boundaries and reaction temperatures of the constituent binary systems, and the available ternary Sn-In-Cu data in the literature. No ternary compound was found in the as-cast alloys. The Sn-In-Cu liquidus projection has 11 primary solidification phase regions and seven ternary invariant reactions with the liquid phase, and g-(Cu 6 Sn 5 ,Cu 2 In) has a very large compositional regime as the primary solidification phase. A very interesting phenomenon that was also observed is that the solidification paths of some Sn-In-Cu alloys surpass the liquidus trough after their intersections.

The η-Phase Field of the Cu-In System.-Selected area electron diffraction and powder XRD are used for the title studies performed in the region 30 to 50 at.% In at temp. ranging from 250 to 500 • C. In the η-phase field three distinct phase regions A, B, and C based on the superstructures of the B8-type are observed and their patterns are discussed. -(ELDING-PONTEN, M.; STENBERG, L.; LIDIN, S.; J.
