Abstract

Al-Ti diffusion couples prepared by resistance spot welding are annealed at 575°C for different time. The microstructure of the interface area was investigated. The result shows that there is no obvious intermetallic compound in the interface after welding. According to the SEM (scanning electron microscope) images, a continuous reaction layer is generated between Ti and Al matrix, and the thickness of the reaction layer increases with the annealing time goes by. A SEM equipped with energy dispersive X-ray spectroscopy (EDX) is used to identify the compounds of the reaction layer. The phase of the reaction layer is TiAl3, which is a kind of Al/Ti intermetallic compound (IMC).
