Properties of Cu-10Cr-2Zr In-situ Deformation Composite
Cu-10Cr-2Zr in-situ deformation composite was prepared by the forging in air and the in-situ production technique.The mircrohardness,tensile strength,microstructure and electrical conductivity Cu-10Cr-2Zr in-situ deformation composite were studied at different strain capacity and intermediate heat treatment temperature.The results showed that Cr and Zr phases of composites changed into fibers from as-cast dendrites with the increasing of the strain capacity,Cu-10Cr-2Zr in-situ deformation composite can obtained the tensile strength higher than 950 Mpa,and electrical conductivity higher than 73%IACS by adjusting intermediate heat treatment temperature,and the best rang of intermediate heat treatment temperature is 450～500 ℃.
