摘要(Abstract)：

采用金相显微镜、电子背散射衍射(EBSD)技术、电化学工作站和人工海水全浸实验等研究了工业生产中使用的热处理制度对B10铜合金弯头微观组织和耐蚀性能的影响。结果表明：热处理过程中B10铜合金弯头发生了晶粒长大和再结晶，再结晶促进孪晶生成，并降低了弯头的硬度和织构强度；弯头内弧由于塑性变形程度更大，热处理阶段再结晶更为明显，因此内弧相比于外弧晶粒更为细小，退火孪晶含量更高；根据电化学测试结果，热处理前后弯头的腐蚀电位、电化学阻抗值均在同一水平且相差很小；热处理后B10弯头的整体腐蚀倾向降低，但热处理后试样击穿电位下降、局部腐蚀敏感性提升，热处理态试样全浸腐蚀速率略高于成型态试样。
