Fine wires approximately on the order of 0.1 mm in diameter have become popular for mechanical and electrical applications. In general, it is well known that finely drawn wires have high strength while maintaining ductility. It has been determined that a hardened layer of approximately 0.04 mm depth, referred to as the "additional shear strain layer," is generated beneath the surface layer of fine wires during drawing. By performing tensile tests on fine wires, with and without the additional shear strain layer, the effect of this layer on the strength and ductility of fine wires was investigated. The tensile strength decreased as the surface layer was removed in all the wires. The additional shear strain layer affected the tensile strength of the fine wires markedly.
