R60702/TA2爆炸焊接复合板的微观组织及力学性能（英文）
|
摘要
通过爆炸焊接的方法实现了R60702板与TA2板的结合。利用光学显微镜、扫描电镜、能谱仪、显微硬度计对热处理前后锆-钛结合界面的微观组织、元素扩散、显微硬度进行了分析;研究了热处理前后复合板的力学性能和断口形貌。结果表明:爆炸焊接后,锆-钛结合界面呈波状,界面附近产生塑性变形和轻微的元素扩散,随着塑性变形的减弱,界面两侧显微硬度也逐渐减小。热处理后,界面元素扩散明显,组织发生再结晶,显微硬度、抗拉强度、抗剪切强度较热处理前降低,而复合板的塑韧性得到提高。热处理后的复合板弯曲性能良好。
R60702 plate and TA2 plate were successfully bonded together by explosive welding. The microstructure, element diffusion, microhardness changes near the bonding interface before and after heat treatment were investigated using optical microscopy(OM), scanning electron microscopy(SEM), energy dispersive spectroscopy(EDS) and microhardness tester. The mechanical properties and fracture morphology in initial and heat treated states were examined as well. The results demonstrate that after explosive welding, the explosively welded bonding interface has a wavy appearance, obvious deformations and slight element diffusion. The microhardness values decrease gradually with increasing the distance to the interface due to the diminishing plastic deformation. After heat treatment, a diffusion layer and recrystallization appear in the microstructure. The overall microhardness values, tensile strength, and shear strength decrease while the plasticity and ductility improve compared with in the initial state. The explosively welded R60702/TA2 composite plate shows a good bending performance after heat treatment.
