Microstructure and Texture of Rolled Cu-0.2wt%Cr-0.5wt%Zr-0.1wt%RE(La)

Abstract:

Cu-0.2wt%Cr-0.5wt%Zr-0.1wt%RE(La) was prepared by casting, quenching, rolling and aging. The microstructure was studied by electron microscope and the texture components were studied by electron backscattered diffraction. In the cast alloy, pure chromium distributed near the grain boundary as a strip shaped and Cu5Zr phase distributed in the interior of grain as a shape of granules. The texture components of the rolled plate include {110} and {112}. With the rolling ratio increased, {112} texture component became the primary rolling texture component. The strengthening effect was attributed to the refinement of the grain size. The electron conductivity was mainly affected by the misorientation of the grain size with a high rolling ratio.
