Abstract
The application of hydrostatic extrusion processing to composite wire fabrication offers several advantages over conventional reduction techniques. These include enhanced uniformity, increased reduction capability, and successful extrusion of normally brittle materials. Specifically, this work involved an experiment to screen the effects of seven extrusion process parameters on the uniformity and density of as-extruded BSCCO-core wire, and the required extrusion pressure. Results suggest the following factors to be potentially significant: 1) back pressure, extrusion ratio, and die angle on core uniformity, 2) packing method, extrusion ratio, silver powder additions, and temperature on density, and 3) extrusion ratio and temperature on extrusion pressure.
