Abstract: We have studied the formation of recrystallization texture in three-layer Ni–5% W/Ni–11% Cr composite tapes obtained through cold rolling to 98.4–99.3% followed by high-temperature annealing at 1000–1150$^\circ$C. It is established that the textured three-layer composite tapes can be used as substrates for creating second-generation high-temperature superconductor (HTS) ribbons. Estimation of the magnetic properties of as-annealed composite tapes showed that their magnetization at HTS working temperatures is lower than that of widely used commercial Ni–5% W alloy tapes.
