摘要
采用电阻炉对爆炸焊接钛．铝复合板进行退火处理，利用万能材料试验机、SEM、EDS和XRD研究了退火工艺对爆炸焊接钛铝复合板组织与性能的影响。结果表明，在400℃退火时，保温时间3～10h对钛一铝复合板界面的剪切强度的影响不大；当退火温度≥450℃时，随着保温时间的延长，复合板的剪切强度开始逐渐上升，到达一峰值后，随着保温时间的继续延长，界面剪切强度开始下降。爆炸焊接钛-铝复合板在450℃、保温时间I〉10h和490℃、保温时间≥3h退火处理时，界面结合区有中间化合物Al3Ti生成。爆炸焊接钛．铝复合板合适的退火工艺选为450℃保温3h。
The explosive-welded titanium-aluminum composite plate was annealed using resistance furnace. Universal material testing machine, SEM, EDS and XRD were used to investigate the effect of annealing process on the microstrncture and properties of titanium- aluminum composite plate. The resuhs show that the holding time （3-10 h） has little effect on the shear strength of titanium-aluminum composite plate which annealed at 400 ℃. However, when the annealing temperature increases to above 450 ℃, along with the prolongation of holding time, the shear strength of titanium-aluminum composite plate increases gradually to a peak firstly and then decreases. There is intermediate compound of A13Ti formed in interracial bond zone when the titanium-aluminum composite plate annealed at 450 ℃ with holding more than 10 h, or at 490 ℃ with holding more than 3 h. The appropriate annealing process of explosive-welded titanium-aluminum composite plate is heated at 450 ℃ holding for 3 h.
