Critical temperatures T/sub c/ and critical currents I/sub c/ under uniaxial tensile loading have been studied on multifilamentary Nb/sub 3/Al wires fabricated by a newly developed composite diffusion process. Both T/sub c/ and I/sub c/ are monotonically decreased with applied strain, showing reversible behavior up to fracture strains of the wires at about 1.3%. These characteristics may be attributed to the composite wire structure, namely to the small difference in thermal contraction between the niobium matrix and the Nb/sub 3/Al filaments, as well as to the extremely small sizes of the Nb/sub 3/Al filaments.
