| Abstract: | The effect of different rare earth element additions in conductive copper is studied. The results show that rare earth element added can change the morphology of the nonmetallic inclusions and refine the grain in conductive copper, so that its mechanical properties are increased. If moderate rare earth elements add in conductive copper, the regular of impurties distribution is changed and growth rate of the grain is suppressed, resulting in improving of conductive properties of copper. |
