Powder metallurgy processed multifilamentary Cu‐Fe, Cu‐Ni, and Nb‐Ni ferromagnetic composite wires were fabricated with a relatively high coercive fieldHcat room temperature. Compacts of Cu‐36 wt. % Fe, Cu‐36 wt. % Ni, and Nb‐36 wt. % Ni powders were reduced in cross section to produce ferromagnetic multifilamentary materials. Nominal areal reduction ratios of 108for Cu‐36 wt. % Fe and 104for Nb‐36 wt. % Ni and Cu‐36 wt. % Ni resulted in values ofHc∼195 Oe, 94 Oe, and 77 Oe, respectively. A final 300 °C anneal of the Cu‐36 wt. % Fe composite gaveHc∼460 Oe. The average ferromagnetic fiber diameters are estimated to be 100–1000 A˚ for the Fe fibers and are about 1 &mgr;m for the Ni fibers.
