Microstructure and Mechanical Properties of Cu-15 ％Cr-0.1Zr Fiber Composite
Cu-15Cr in situ composite was fabricated by cold drawing and intermediate heat treatments. Result of experiments on Cu-15Cr-0.1Zr alloy demonstrate this fabricate filamentary composites with ultimate tensile strengthen reached about 1200MPa, electric conductivity reached about 73％IACS. The evolution of filamentary microstructure and mechanical properties were investigated for the alloy at different draw ratio. With the increasing draw ratio, the dendritic with a discontinuous distribution develop into fine fibrous bundles to result in the increase of the strength. The influence of different intermediate heat treatment on properties was studied, and the results suggest that Cu-15Cr -0.1 Zr which have good combination of strength and conductivity can be obtained through controlling draw ratio, adjusting intermediate heat treatment technical.
