形变与热处理对CuCr合金中Cr相形貌及合金性能的影响 郝文光1,肖莹2,常立民3 (1.北京电力设备总厂,北京,102401;2.燕山大学,河北,秦皇岛,066004;3.吉林师范大学,吉林,四平,136000) 摘要:研究了CuCr合金在不同形变与热处理制度下,组织中Cr相形貌,合金力学性能及导电性能的变化.结果表明:当变形量达到70%时,合金中的Cr粒子产生严重的变形,且有开裂现象.在随后高温热处理过程中开裂的Cr粒子发生熔断和球化.适当的形变与热处理能改善CuCr合金的力学性能与导电性能,并从微观组织方面对其原因进行了分析. 关键词:CuCr合金; 形变与热处理; Cr相; 力学性能; 导电性能; [全文内容正在添加中] ......
solution. So, CuCr alloy is a kind of machinery-mixed composite material, and the solid solubility of Cu and Cr phase is very low. Cu has lower melting point, high electrical conductivity, high temperature conductivity and good plasticity, which will be helpful to improve the breaking current capacity and rated current of CuCr alloy. Cr provides a good voltage withstand property and anti-corrosion......
