超细晶铜铬合金的制备及应用研究进展OA

Copper chromium alloy,as a new type of functional material,has broad application prospects in high-speed train overhead contact lines,semiconductor lead frames,generator conductive rings,etc.due to its high hardness,excellent conductivity,and wear resistance.Compared to coarse-grained Cu-Cr alloys,ultrafine grained Cu-Cr alloys often exhibit superior comprehensive properties and are a research hotspot in the field of conductive copper alloys.Based on the manufacturing process and latest research of Cu-Cr alloy,this article systematically summarizes the processing technology and application research of ultrafine grained Cu-Cr alloy,and discusses in detail the optimization and improvement of the microstructure and properties of Cu-Cr alloy by severe plastic deformation.Furthermore,the future development trend of ultrafine grained Cu-Cr alloy is analyzed.
