Abstract

In this work, effects of varying mechanical deformations on the relationship between mesotexture and current percolation in (Bi, Pb) 2Sr2Ca2Cu3O10+x (Bi2223) tapes are investigated. Electron backscattered diffraction analysis demonstrates that the mesotexture distribution characteristics influence critical current density (Jc) as results of the processing variations. The disorientation angle distribution dependence of Jc is also discussed using current percolation theory. The results show that improving the mesotexture distribution in central region of Bi2223 tapes through optimization of the mechanical deformation processing can significantly increase Jc.
