Phase Diagram of the System InBiSn.

Abstract

The phase diagram of the system InBi-Sn has been determined by thermal analysis, metallographic, and x-ray procedures. A eutectic is formed at 81°± 0.2°C ., containing 16.3 ± 0.1% Sn and 83.7% InBi. The solid solubility of Sn in InBi is less than 0.1%. Sn dissolves 42% InBi at 81°C. and 20% at 71°C. An X-RAY and microscopic study of portions of the ternary system In-Bi-Sn showed that the InBi phase and Sn solid solutions coexisted over most of the compositional range of the InBi-Sn pair and that the two formed a quasi-binary section. The nature of this phase diagram was established by thermal analysis, x-ray, and microscopic examination. EXPERIMENTALMaterials. The indium (on loan from the Indium Corpora-

Thermodynamic re-optimisation of the Bi–In–Sn system based on new experimental data

“…4-7 with experimental data from literature being included. From these vertical sections one can conclude that the experimental points from [7,8,10,11,14] characterising the liquidus and solidus line agree well with the corresponding calculated values. The calculations also verify the results of [11] and [12], regarding the conclusion that both BiIn-Sn and BiIn 2 -Sn systems (see Fig.…”

“…Vertical sections BiIn-Sn (a) and BiIn 2 -Sn (b). Points in (a) are experimental data from [14], while in (b) open circles are experimental data from [7] and solid circles from [8], respectively. Calculated vertical sections through the Bi-In-Sn system are displayed in Figs.…”

“…[11] and Moelans et al [12], stemming from thermal analysis, light optical microscopy, XRD , SEM and EDX data of [6][7][8]10,11,13,14]. Additionally to these, all data obtained experimentally in [1] and in the present work were equally used.…”

The effect of growth rate on microstructure and microindentation hardness in the In–Bi–Sn ternary alloy at low melting point

“…Alloys of eutectic composition may also serve as model alloys for the investigation of pattern formation during directional solidification of eutectics [2][3][4][5][6]. Previous studies indicate that several invariant reactions exist in this alloy system at temperatures below 373 K [7][8][9].…”

Structure and thermal expansion mechanism of liquid InBi compound

“…Besides, the Bi22-In eutectic alloy is also proposed to use for diffusion soldering of copper substrates [6]. For these alloys, as it follows from phase diagrams [7][8][9], the formation of InBi intermetallic phase is observed.…”
