“…Another alternative is Sn-Zn solder alloy (Zn about 9 wt%) with a melting point of about 198 • C [16][17][18][19]. This alloy offers significant benefits in terms of cost and the good mechanical properties on Sn-Zn solder alloy [16,17].…”

“…According to Kanlayasiri and Ariga [22], Bi and In can be employed to lower solidus and liquidus temperatures of solder alloys. Therefore in the past several years a number of studies have been carried out on the binary, ternary and quaternary systems of low temperature soldering such as Sn3.13Ag0.74CuIn [23], Sn-Zn-Bi [24,25], Bi.22In [26], Sn-Zn [17][18][19]27,28], Sn-Zn-xBi [29], and Bi-In-Zn [30]. Although lead-free solder has been extensively studied, information about the In-31.6Bi-19.6Sn solder alloy is not yet available in the literature.…”

“…Among the three principal elements in the matrix phase, the NSPs had the most positive mixing enthalpy. 12,13 Because the DSPs and BSPs have a weaker mixing enthalpy, it is virtually impossible to prevent the segregation of Zn rich phase during prolonged cooling in either the gypsum or graphite moulds. As a result, DSPs and BSPs are formed among the Zn rich and matrix phases.…”

“…5) because Sn has a higher affinity for Sn than to any of the other elements in the Sn-9Zn solder system. 3,4,7,13,18,21 In all specimens, the amount of Zn rich phase is an indication of the competing effects associated with the affinity between the Sn, Zn and In atoms and the diffusion force of Sn and In atoms and depends on the crucible environment. Because the needle shaped and droplet shaped structures are thin, we determined that the formation of the Zn rich phase was dominated by the affinity between the Zn and Sn atoms, and thus the Sn and In diffusion forces are relatively low.…”

To cite this article: C-M Lin (2013) Influence of thermal storage on microstructure and properties of Sn-9Zn-xIn alloys, Canadian Metallurgical Quarterly, 52:1, 98-105,This study investigated the solidification behaviour and microstructural properties of Sn-9Zn-xIn alloys cooled under various crucible environments (i.e. gypsum or graphite moulds). Sn-9Zn-xIn solder specimens were prepared with the addition of In ranging from 0 to 0?5 wt-%. The specimens were melted at 200uC, poured into gypsum or graphite moulds and then allowed to cool in air. The microstructure, chemical composition and hardness properties of various specimens were then systematically examined. It was found that the microstructure (and hence the mechanical properties) of the solder samples can be controlled by manipulating the variables of the solidification process, such as cooling rate, element diffusion rate, solubility among elements and the crucible environment.Cette é tude a examiné le comportement de solidification et les proprié té s de la microstructure des alliages Sn-9Zn-xIn refroidis dans divers creusets (c'est-à -dire des moules en plâ tre ou en graphite). On a pré paré des spé cimens de soudure de Sn-9Zn-xIn avec des additions d'In variant de 0 à 0?5% en poids. Les spé cimens é taient fondus à 200uC, coulé s dans des moules en plâ tre ou en graphite, et ensuite refroidis à l'air. Ensuite, on a systé matiquement examiné la microstructure, la composition chimique et la dureté des divers spé cimens. On a trouvé que l'on pouvait contrôler la microstructure (et ainsi les propriétés mé caniques) des é chantillons de soudure en manipulant les variables du procé dé de solidification, comme la vitesse de refroidissement, la vitesse de diffusion de l'élé ment et la solubilité entre les é lé ments ainsi que la nature du creuset.

“…The integral enthalpy of mixing was calculated by summarizing the respective reaction enthalpies and dividing by the total molar amount of substance. The respective binary starting value for each section in the ternary system was calculated from the binary literature data[ 24 , 32 , 40 ] using the interaction parameters listed in Table 3 .…”

The partial and integral enthalpies of mixing of liquid ternary Ni-Sn-Zn alloys were determined. The system was investigated along two sections xNi/xSn ≈ 1:9, xNi/xSn ≈ 1:6 at 1073 K and along two sections xSn/xZn ≈ 9:1, xSn/xZn ≈ 4:1 at 873 K. The integral enthalpy of mixing at each temperature is described using the Redlich-Kister-Muggianu model for substitutional ternary solutions. In addition, the experimental results were compared with data calculated according to the Toop extrapolation model. The minimum integral enthalpy of approx. −20000 J mol-1 corresponds to the minimum in the constituent binary Ni-Sn system, the maximum of approx. 3000 J mol-1 is equal to the maximum in the binary Sn-Zn system.
