Abstract
A new deformation method for the fabrication of in situ composites is described. It is found that intensive simple shear, performed repeated ly in the same direction, transforms ductile second phase particles in to aligned filaments. Processing is performed by multi-step equal chan nel angular extrusion (ECAE). Results of experiments on Cu-18Nb and Cu -25Ag alloys demonstrate the ability of this method to fabricate filam entary composites from cast bulk products with no change in the work p iece cross-section.
