With1,10-phenanthroline as the conceal agent and Tritonx-100as the emulsion,directly measuring the zirconium content in the zirconium-chromium copper wire through arsenazoⅢ,this way used to measure such im portant content in this new material for the AC drive locomotives is very effective and reliable,and get a satisfied re-sult.

This paper studies the flow stress of chrom copper by experiment with the cam plastometer at a constant deformating rate, and analyses the effeets of flow stress under different deformation temperatures,different deformation rates and different deformation degrees.
