“…10) The faceting lamellas are Zn and the non-faceting phase is the Sn solid solution. Under rapid cooling conditions, the lamellar Zn becomes fibrous, 10,11) which means the sensitivity to solidifying conditions. It is considered that electrical and thermal conductivity of SnZn eutectic system alloys are difficult to be estimated using Maxwell 12) and Landauer 13) models, because those properties are directly influenced by morphology of each phase in them as described in Fan's model.…”

The addition of 8 vol% Al 2 O 3 in Zn50 mass%Sn, was carried out for the control of electrical and thermal properties, for Pb-free fuse elements used in electric power line. The distribution-control of Al 2 O 3 particles in Zn50Sn was carried out by the varying process parameters such as the temperature and period for Al 2 O 3 -addition and -stir in its melt or semi-solid. Homogeneous and heterogeneous Al 2 O 3 -distributions were achieved in microstructure consisting of primary Zn and eutectic, which meant the location of Al 2 O 3 in both regions and only eutectic in constituent phases, respectively. The temperature dependence of specific resistivity, thermal conductivity, specific heat and density was measured for electrical and thermal calculations to obtain the temperature distribution in fuses. The values on their properties were determined depending on Al 2 O 3 distributed states in alloys. Both the melt and un-melt down performance for AC-low voltage fuse elements could be satisfied on both Zn50Sn alloys with different distribution of Al 2 O 3 , and the superior performance was shown in the homogeneously Al 2 O 3 distributed alloy.

Control of Electrical and Thermal Properties on Sn–50Zn Alloy by 8 vol%Al2O3 Addition for Pb-Free AC-Low Voltage Fuse Elements

The addition of 8 vol%Al 2 O 3 particles in the Sn50Zn was carried out for the control of electrical and thermal properties, for Pb-free fuse elements used in electric power line. The metal matrix composite of the SnZn alloy and Al 2 O 3 particle having the different densities and melting points could be produced by the handling at coexisting range of both liquid and solid phases and showed the homogeneous microstructure of randomly dispersed Al 2 O 3 via ingots. The temperature dependence of specific resistivity, thermal conductivity, specific heat and density was measured to use their values in electrical and thermal calculations in order to obtain the temperature distribution on Pb-free fuse elements. Both the melt and un-melt down performance of main requirements for AC-low voltage fuse elements could be satisfied on the Sn 50Zn8 vol% Al 2 O 3 element.

“…Numerous efforts has been made to develop lead (Pb)-free solders that are intended to be an alternative for the long-established family of Pb-containing solder alloys (Ref [1][2][3]. Due to a low cost coupled with melting point close to that of conventional Sn-Pb solders, the Sn-Zn-based alloys are recognized as a possible replacement for high Pb-containing solders that are still commonly used, particularly for high-temperature applications ( Ref 1,[4][5][6][7][8]. Therefore, studies on factors affecting material properties of these alloys are underway (Ref [2][3][4][5][6].…”

The research was undertaken to establish mechanical properties of as-cast and heat-treated Sn-Zn-based alloys of binary and ternary systems as candidates for lead (Pb)-free solder materials for high-temperature applications. The heat treatment of as-cast alloys was made under different combinations of processing parameters (168 h/50°C, 42 h/80°C, and 24 h/110°C). The systematic study of structure-property relationships in Sn-Zn, Sn-Zn-Ag, and Sn-Zn-Cu alloys containing the same amount of Zn (4.5, 9, 13.5 wt.%) and 1 wt.% of either Ag or Cu was conducted to identify the effects of chemical composition and heat treatment processing parameters on the alloy microstructure and mechanical behavior. Structural characterization was made using optical microscopy and scanning electron microscopy techniques coupled with EDS analysis. Mechanical properties (initial YoungÕs modulus E, ultimate tensile strength UTS, elastic limit R 0.05 , yield point R 0.2 , elongation A 5 , and necking Z) were determined by means of static tensile tests. All the examined Sn-Zn-based alloys have attractive combination of mechanical characteristics, especially tensile strength, having values higher than that of common leaded solders and their substitutes of Pb-free SAC family. The results obtained demonstrate that the Sn-Zn-based alloys present competitive Pb-free solder candidates for high-temperature applications.
