摘要
采用组织分析和性能检测手段,研究了不同中间退火工艺对采用高通量连铸连轧技术生产的AA5052-H32成品板折弯及成形性能的影响.结果表明:优化中间退火工艺可有效提升成品板材的成形性能,在经480℃×8 h的中间退火后,成品板材折弯性能最好,成形性能得到改善;高温中间退火后,部分第二相颗粒在高温均匀化的作用下回溶,对基体的割裂作用降低,成形性能得以改善.
The influence of different intermediate annealing processes on bending and forming performance of AA5052- H32 sheet by high-throughput continuous casting and rolling was investigated by texture analysis and performance testing. The results show that： the optimized intermediate annealing process can effectively improve the formability of final products. By annealing at 480℃ for 8 h,the bending performance of final plate reaches the best,forming performance is also improved. Intermediate annealing at high temperature can dissolve part of the second phase by the effect of high temperature homogenization,and improve the formability of sheet.
