夹层爆炸焊接高强度铝合金与钛合金的界面特性和力学性能研究
The study of interface characteristics and mechanical properties of explosive welding of high-strength aluminum alloy and high-strength titanium alloy
摘要
Abstract
To achieve explosive bonding of high-strength low-melting-point aluminum alloy(A7075)and high-strength titanium alloy(Ti-6Al-4V),this study proposes the use of pure aluminum(A1060)as an interlayer and investigates the interface morphology and structural characteristics under different welding parameters.The microstructural features and tensile-bending properties of the composite plate interface were analyzed using optical microscopy(OM),scanning electron microscopy(SEM),and universal material testing machine.Explosive welding of the A7075/A1060/Ti-6Al-4V metal composite plates with interlayer bonding was successfully achieved under both sets of parameters,with no significant defects observed at the welding interface.Melted regions were found at both the upper and lower interfaces under different explosive welding parameters.Mechanical performance results show that the interface shear strength of the composite plate prepared with a 2mm thick A1060 interlayer is greater than 70.3MPa.In terms of bending performance,samples with interlayer gap parameters of 2mm and 5mm exhibited higher bending strength,with the maximum bending strength reaching 1209.9MPa.No fracture occurred at the welding interface during tensile bending tests.This study provides valuable insights into the explosive welding process for this type of composite plate.关键词
