| Abstract: | The microstructure of trace samples of copper wires are observed by SEM.These samples are machine failure,burned melt downs and short-circuit melt down wires and are made through simulation electrical circuit experiments in electrical accidents.The microstucture characteristics and formation mechanism of copper wire are scientifically analyzed and the study provid a powerful reference in judging the fractured reason of copper wires. |
