摘要
Abstract
The effects of cold-extruding treatment on the microstructure and properties of Cu70Cr30 contact composites prepared by combustion synthesis-casting were investigated. The results indicate that the cold-extruding treatment can refine the grain size, improve the electric conductivity, density and hardness of the composites. So it is a desirable approach to improving the microstructure and properties of the composites by extruding treatment.关键词
