在Bi2 2 2 3/Ag超导多芯带材的制备过程中 ,采用了冷压成形的加工工艺。介绍了压力、压下速率、摩擦系数等冷压工艺参数对带材临界电流Ic值的影响 ,本研究所得结果对进一步实现Bi2 2 2 3/Ag多芯超导带材冷压工艺的优化具有指导作用
In the preparation of Bi2 2 2 3 / Ag superconducting multi-core tape, the cold forming process was adopted. The effects of pressure, reduction rate and coefficient of friction on the critical current Ic of strip were introduced. The results obtained in this study have the potential to further optimize the cold pressing process of Bi2 2 2 3 / Ag multifilamentary superconducting tapes Guidance
