| Research Abstract |
The interaction between microstructures and thermal or electric properties was investigated in Sn-Zn alloys. The addition of 8 vol.% Al2O3 in Zn-50mass%Sn, was carried out for the control of electrical and thermal properties, for Pb-free fuse elements used in electric power line. Homogeneous and heterogeneous Al2O3-distributions were achieved in microstructure consisting of primary Zn and eutectic. The temperature dependence of specific resistivity, thermal conductivity and specific heat measured for electrical and thermal calculations. The values on their properties were determined depending on Al2O3 distributed states. Both the melt and un-melt down performance for AC-low voltage fuse elements could be satisfied on both Zn-50Sn alloys with different distribution of Al2O3. Cu/Al2O3-Zn-50Sn fuse elements including of partiaclly compositional gradient layers were prepared successfully by spark sintering. Their junction elements showed excellent melt and un-melt down performance.
