摘要(Abstract)：

采用透射电镜(TEM)、电子背散射衍射(EBSD)技术和拉伸试验等研究了退火温度对冷轧态C19400合金组织性能与残余应力的影响。结果表明：随退火温度的升高，合金的导电率变化不大，强度和硬度先升高后降低；冷轧态合金的强度和硬度分别为424.4 MPa和132.0 HV0.1;250℃退火后，合金的强度和硬度分别为433.85 MPa和141.92 HV0.1;450℃退火后，强度和硬度分别为420.6 MPa和139.7 HV0.1;合金的残余应力随退火温度的升高呈下降趋势，450℃退火后合金的横向和轧向残余应力分别由冷轧态的-36和-66 MPa降低到-13和-29 MPa,位错的湮灭及织构类型的转变是残余应力消减的关键。退火过程中，C19400合金发生由退火硬化向退火软化的转变。

关键词(KeyWords)： C19400合金;残余应力;组织性能;织构
