Research on the Characteristics of Ti-Al Composite Tube by Explosive Welding

摘要：

　　Ti-Al composite tube has the merits of high hardness, corrosion resistance, heat resistance and low specific gravity;and is widely used in aerospace industry, petroleum industry, and nuclear industry.Explosive welding is used to produce the Ti-Al composite tube in this paper.The effect of Sodium chloride emulsion explosive and detonation velocities on the interface characteristics are investigated.The bond interface wave and mechanical properties are analyzed.From the Scanning Electron Microscopy (SEM), it can be found that the interface is wavy, which can produce best welding characteristics.And detonation velocity has great effect on the bond interface wave.Mechanical tests including the flattening test, compression test, and bending test are conducted on the Ti-Al composite tube.Research showed that the interface bond properties and strength can fully withstand large plastic deformation.
