Abstract
Controlled fracture forming(CFF) of metal/alpha-alumina composite wires and fibers was mainly studied with respect to the strength of alumina resintered into composite wires sheathed by nickel or austenitic stainless steel. The hardness of resintered alumina decreased with total reduction of cold working, because the densification of alumina should be prevented by contamination of sheath-metal constitutive elements during processing. In order to improve this resinterability, pure aluminum foil was inserted into the interface between metal sheath and presintered alumina, and worked by CFF processing. These green composite wires were resintered at 1623K for 3.6ks in nitrogen atmosphere. This processing is effective to fabricate dense alpha-alumina/metal composite wires and fibers to be used in practical applications.
