摘　　要：在实验室模拟不同退火温度下冷轧BH铜的力学性能及金相组织变化。利用强度示差分析法确定BH铜再结晶温度，并经大生产实践验证确认；在此基础上，进一步确定了BH铜最优退火温度。The changes of mechanical properties and microstructure of cold rolled BH steel were simulated in the laboratory under different annealing temperature. By means of differential strength analysis method , BH steel recrystallization temperature was determined, and in practice, confirmed by the large--scale production; on this basis, further defined the optimal annealing temperature of BH Steel.
