对铸态Cu-38.13Zn-0.21Al合金进行l~5 GPa,720℃保温20 min的高温高压处理,采用热常数测试仪和赛贝克电阻率测试仪测试了高温高压处理前后Cu-38.13Zn-0.21Al合金的热扩散系数及电阻率,用光学显微镜和透射电子显微镜对其微观组织进行观察,并根据实验结果探讨了高温高压处理对Cu-38.13Zn-0.21Al合金热扩散系数及电阻率的影响.结果表明:高温高压处理能细化合金组织及增大组织内位错密度,使其热扩散系数降低和电阻率升高,在l ~5 GPa范围内,压力为3 GPa时,热扩散系数达到最低值,为0.3024 cm2·s-1,较铸态样品的值降低了14.79%,而电阻率达到最高值,为7.657×10-8 Ω·m-1,较铸态样品的值增大了7.48%.
