SPD Procedure and High Performance of Ultrafine-Grained Cu-Mg Alloy for Electrical Railway

Continuous Con-form plus equal-channel angular pressing (EACP) was applied to produce ultrafine-grained Cu-Mg contact wire materials with high strength and good conductivity, aim to push back the catenary barrier of high-speed trains by maximizing the tension and improving the power delivery. Micros...
