Abstract

A Ti-Nb superconducting alloy forming a beta-solid solution phase is warm aged below the beta-phase solubility limit, e.g. at between 200 and 700 DEG C. for between 15 minutes and 10 hours, to precipitate a dispersed finely divided second phase, e.g. comprising alpha-Ti, in the alloy matrix to increase superconducting current density in high magnetic fields. Prior to warm ageing, the alloy is beta-solid solution annealed, e.g. by heating at 800 DEG C. in vacuum and water, oil or air quenching, and preferably cold worked, e.g. into wire or strip, for high field solenoids, by rolling, swaging or drawing. The binary Ti-Nb alloy may be modified by adding an element forming a beta-eutectoid type phase diagram with Ti, e.g. Bi, B, Cr, Co, Cu, Au, Fe, Pb, Mn, Ni, Si, Ag or U, to precipitate on warm ageing an intermetallic compound of the element and Ti as a dispersed second phase in the alloy matrix. Alternatively, an alpha-titanium stabilizing element such as Al, Ga, Ge, La or Ce may be added to the alloy to raise the alpha to beta transformation temperature of Ti, so that on solution heating in the beta region e.g. by homogenizing at 600-1600 DEG C., quenching and warm ageing within the alpha-beta region e.g. at 400-1000 DEG C., alpha-Ti is precipitated as a dispersed second phase in the alpha-beta alloy matrix. The alloy may have a composition of 10 to 70% by weight Nb, balance Ti, the additive element if present ranging from 1 to 10% by weight.
