A 'solid-state precipitation' process was used to prepare superconducting tapes containing Nb{sub 3}Al in a niobium matrix. Small ingots of Nb-(17-19 at.%)Al were prepared by arc melting, homogenizing, quenching, warm rolling into tape, and aging at 750-900 C to precipitate the A15 phase. Transmission electron microscopy studies revealed Nb{sub 3}Al precipitation in fine particles which formed a semicontinuous network over subgrain boundaries formed by the recovery of deformation-induced dislocations. Promising high-field critical currents were obtained (J{sub c}-10{sup 4} A/cm{sup 2} in a field of 14 T at 4.2 K)
