Deformation Processed Cu-15 wt pct Cr Composite Synthesized by Hot Hydrostatic Extrusion of Mechanical Milled Powders

Keywords： Mechanical milling

A novel technique was developed for the preparation of Cu-15 wt pct Cr composite with high strength and conductivity.The composite powders with refined microstructure and curly lamellae strengthening phase was first prepared bymechanical milling in favorite milling time and then were hot hydrostatic extruded after pre-densification with sinteringor hot pressing. It was shown that the extrusion densified the composite powders well and at the same time the chaoscurled strengthening phase was aligned into lines and further deformed as strengthening ribbons. The deformationprocessed Cu-15 wt pct Cr composite prepared by this technique is of superior conductivity, strength and thermalstability.
