Overview

V- Ti alloys are promising alternatives to Nb for the construction of superconducting solenoids that produce high magnetic fields. The critical current density ( J C ), which quantifies the capacity of a superconductor to carry large dissipationless current, increases in the V-Ti alloys with the addition of Ce. Here, the effects of successive cold working and annealing on the electrical resistivity, J C , and microstructure of the V 0.59 Ti 0.40 Ce 0.01 alloy are studied. The J C is the maximum after the second cold rolling. Annealing at 650 ∘ C is found to nucleate and grow the α -phase which is detrimental to J C , whereas the precipitation of the α ′ -phase is found to improve the J C .
