Description

This paper deals with the wire breaking problems during the fabrication of composite wire. The global objective is the establishment of sound guidelines for the design of the composite wire and of the pass-reduction practices that will lead to the fabrication of high-quality defect-free wire in a reproducible cost-effective manner. The ranges of processing parameters (geometric, material strength ratios, and pass-reduction schedules), which lead to successful products without filament breaks, is determined analytically. A quantitative criterion for the selection of the range of parameters is provided.
