Abstract

Mechanical working of a single phase superconducting alloy leads to an increase in the critical current density,J c, After cold-rollingJ c exhibits anisotropy as the angle of the magnetic field to the rolled surface is changed.

This paper studies the effects of interstitial addition and heat-treatment onJ c and its anisotropy in both cold-rolled and wire-drawn alloy. The variations inJ c are correlated with the observed changes in the microstructure.
