Description

The influence of combined deformation, including equal-channel multiangle pressing (ECMAP), and heat treatment on the critical current density of a superconducting wire made from the alloy Nb+60 at. % Ti is investigated. It is found that the combined deformation, including ECMAP, can increase the critical current density by up to two times. The relationship between the character of the structural inhomogeneities and the pinning force is estimated. The pinning efficiency is linked to the nanostructural state of the alloy
