作为以Cu—Ga合金和V芯复合加工法制取V_3Ga化合物多芯线的基础研究;介绍了复合带材、35芯多芯线材Cu—Ga合金的组织、复合材料的加工性以及V_3Ga的扩散生成研究。通过Cu—Ga固溶合金与V芯的复合材料的加工及热处理认为V_3Ga超导线材是很容易获得的。Cu—Ga固溶合金的加工性是良好的,但当Ga浓度超过20%原子比时,则有走相析出使其合金硬度增加,故冷加工很困难。Cu—Ga合金熔体与V芯适于 As a basic research on the preparation of V 3 Ga compound multi-core wire by Cu-Ga alloy and V core composite processing, the structure of composite strip, 35-core multi-core wire Cu-Ga alloy, the processability of composite materials and the diffusion of V 3 Ga the study. Through the processing and heat treatment of composite materials of Cu-Ga solid solution alloy and V core, V_3Ga superconducting wire is easily obtained. The workability of the Cu-Ga solid solution alloy is good, but when the Ga concentration exceeds 20 atomic%, the phase precipitation is caused to increase the hardness of the alloy, so that cold working is difficult. Cu-Ga alloy melt and V core suitable
