Thermal conductivity and properties of sheath alloy for High-$T_c$ superconductor tape
고온초전도 선재용 피복합금의 열전도도 측정 및 특성평가
Abstract
Effect of alloying element additions to Ag on thermal conductivity electrical conductivity and mechanical properties of sheath materials for BSCCO tapes has been characterized. The thermal conductivity at low temperature range(10~300K) of Ag alloys were evaluated by both direct and indirect measurement techniques and compared with each other. It was observed that thermal conductivity decreased with increasing the content of alloying elements such as Au, Pd and Mg. Thermal conductivity of pure Ag at 30 K was measured to be 994.0 W/m.K on the other hand the corresponding values of A
