A ’’solid‐state precipitation’’ process was used to prepare superconducting tapes containing Nb3Al 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 Nb3Al precipitation in fine particles which formed a semicontinuous network over subgrain boundaries fromed by the recovery of deformation‐induced dislocations. Promising high‐field critical currents were obtained (Jc∼104 A/cm2 in a field of 14 T at 4.2 K).
