采用显微硬度分布（hv0.01）对不同变形工艺后的BSCCO/Ag金属丝和银带的横截面密度进行监测。得到的结果有助于更好地理解BSCCO/Ag复合材料的变形过程，也表明了采用管内粉末法获得均匀致密的BSCCO-芯应采用何种变形。自场输运电流测量表明，要达到足够高的输运电流，磁芯密度必须达到最佳值。如果织构不改善，致密的陶瓷芯不足以达到高的J/sub / c/。
The monitoring of density by microhardness profiles (HV 0.01) at transverse cross sections of BSCCO/Ag wires and tapes were done after different deformation processes. The results obtained allow better understanding of deformation process of BSCCO/Ag composite and also show what deformation should be used to obtain homogeneous and dense BSCCO-core by powder-in-tube method. The self field transport currents measurements have indicated that optimal value of core density is needed to reach sufficiently high transport currents. Dense ceramic core is not sufficient to reach high J/sub c/ if texture is not improved as well.
