The equilibrium phase diagram of the copper–indium system: a new investigation

Crystallographic characterization of Cu–In alloys in the 30–37at% In region

“…There are in good agreement with those previously reported by Elding-Pontén et al [15]. Phase A is a superstructure of phases h or η′ (both with identical crystal structure) [8][9][10][11][12] and differs from phases A (PDF 00-026-0523 card) and A′ (PDF 00-026-0522 card) previously reported by Jain et al [9]. At low temperature, the existence of phases B and C is in accordance with the phase diagram proposed by Jain et al [9] while they differ from the only one phase (η) expected from the phase diagram proposed by Bolcavage et al [11].…”

“…1b [11,12]. This diagram indicates that only two phases occur in the 33-38 at% In composition/temperature range, namely η and η′, at low and high temperatures, respectively.…”

Experimental study of the ternary Ag–Cu–In phase diagram

“…As we had earlier undertaken studies of the binary systems Ag-In and Cu-In [1,2], we found it natural to perform a study of the whole ternary system Ag-Cu-In.…”

Liquidus Projection and Solidification of the Sn-In-Cu Ternary Alloys

“…Liu et al 13 agreed with their observations and proposed a thermodynamic model for the continuous solid solution. 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.…”

“…1 are proposed based on the primary solidification phase determinations as summarized in Table I, the liquidus projection determined by Köster et al 11 at the Cu-rich corner, and the phase diagrams of the three constituent binary systems. 7,15,18 Since the experimental determinations by Köster et al 11 at the Cu-rich corner appeared to be reliable to the authors, their experimental results are adopted directly without duplicate efforts.…”
