| Abstract: | The self-made Cu-RE refining agents were used to refine impure-copper.The influences of RE elements on refinements and structures were studied and the effect mechanism of RE was discussed.The results show that by adding proper amounts of Cu-RE refining agents into impure-coppers,the effect of RE on the refinement of impure-coppers is perfect.Furthermore,the dendrite grains of the samples are refined and the structure becomes more homogeneous,so the electric conduction function and mechanical properties of t... |
