    摘要
  • 摘要: 为了解决钛-铝在爆炸焊接过程中可焊性低并容易产生脆性金属间化合物等技术难题，选用低爆速粉状乳化炸药为试验用药，下限装药厚度和上限基复板间距为工艺参数，成功获得了100%复合的“1 + 14 + 1”TA2 - 1060 - TA2双面金属复合板. OM， SEM， EDS测试结果表明，复合板界面呈良好小波状结合；基复板流在波峰阻挡以及复板挤压作用下形成漩涡结构，其内部存在包覆熔融金属的铸锭组织；结合界面附件发生不同程度的元素扩散. 力学测试结果表明，复合板的弯曲强度为288 MPa、抗拉强度为165.5 MPa、界面处显微硬度峰值为227 HV，满足工业生产要求.
    Abstract: To solve technical problems of low weldability and easy generation of brittle intermetallic compounds during titanium-aluminum explosive welding, the low-detonation-velocity powdery emulsion explosive, lower limit of charge thickness and upper limit of distance between the flyer and base plates were determined, thereby successfully manufacturing "1 + 14 + 1" TA2-1060-TA2 double-sided metal cladding plate with 100% welding rate. The results of OM, SEM, EDS tests showed that the interfaces of the cladding plate presented the high quality small wavy bonding; under the action of peak blocking and flyer plate extrusion, the flowing of the base and flyer plates generated the vortex structure where the ingot structure wrapping molten metals were observed; different levels of elemental diffusion took place near the bonding interfaces. The mechanical test results showed that the bending strength, tensile strength and microhardness peak value of the cladding plate were 288 MPa, 165.5 MPa and 227 HV, respectively, which met the requirements of industrial production.
