The growth of the reaction layers at the wire-matrix interface in the annealing temperature range from 473 to 873 K and its influence on the strength of the composite using the uncoated wire and Ni-coated wire were examined.<BR>When using an uncoated wire, the reaction layer was not formed at the wire-matrix interface below about 573 K, and began to form above 673 K. The reaction layer was composed of FeAl₃ and Fe₂Al₅. When using Ni-coated wire composite, the reaction layer was not formed up to 573 K, like an uncoated wire. At temperature above 673 K, NiAl₃ was formed at Ni-coated layer, while FeAl₃ and Fe₂Al₅ were formed at the wire side. The effect of the annealing temperature on the tensile strength of the composite was investigated by annealing at various temperatures for 180 ks. The tensile strength of the uncoated wire composite by annealing decreased about 10 MPa compared with the as-welded one and showed a constant value at 473-673 K. Above 773 K, it decreased drastically. On the Ni-coated wire composite, the same tendency was observed and especially its strength showed a maximum value at 673 K. The high strength at 673 K was discussed on the basis of Cooper and Kelly’s analysis using the result of the transverse test on the single wire composite. In the uncoated fiber composite, the high strength at 673 K annealing was to come from the increasing bonding strength by the interdiffusion at the wire-matrix interface. The Ni-coated wire composite was strengthened not only by the interdiffusion but also by the formation of intermetallic compounds.
