    摘要:

    为减小焊接炸药装药量, 采用间隙配合的Q345燕尾槽钢板与TA2燕尾槽钛板, 分别作为覆板和基板。燕尾槽的上底面、下底面和高分别为2, 3,1 mm。所有燕尾槽的间隔为3 mm。间隙配合的钛板和钢板通过爆炸压接以及热轧得到尺寸为7.0 mm×300 mm×750 mm的钛-钢复合板。用力学性能检测以及微观形貌观察分析复合板界面结合质量。结果表明, 间隙配合的燕尾槽钛板与钢板经爆炸压接-热轧工艺实现冶金结合, 复合板界面结合良好, 界面呈直线形, 无金属间化合物生成, 复合板弯曲性能良好。爆炸压接-热轧法制备钛-钢复合板相比爆炸焊接法可节约62.7%炸药。

    Abstract:

    To reduce the charge amount of welding explosive, TA2 titanium and Q345 steel plates were used as flyer and base plates of dovetail groove, respectively. The upper side length, the lower side length and the height of dovetail grooves were 2 mm, 3 mm and 1mm, respectively. All the intervals between dovetail grooves were 3 mm. The Ti-steel clad plate with dimension of 7.0 mm×300 mm×750 mm was obtained via Q345 steel and TA2 titanium plates with dovetail groove were loosely fitted and bonded by explosive pressure welding and hot rolling technology. Bonding quality at the interfaces of Ti-steel clad plate was analyzed by mechanical property test and microscopic morphology observation. Results show that the metallurgical bonding at the interfaces of TA2 titanium and Q345 steel plates is achieved by explosive pressure welding and hot rolling. Bonding quality at the interfaces of the clad plate is good, and the interfaces exhibit a linear shape, and intermetallic compounds do not occur. The clad plate has excellent bending performance. Compared with explosive welding, the charge amount of Ti-steel clad plate produced by explosive pressure welding and hot rolling may save by 62.7%.
