| Abstract Scope |
Recently, there has been an increasing demand for joining dissimilar metals having different properties in various fields. Especially, dissimilar bonding of Ti6Al4V / STS with high specific strength and excellent corrosion resistance expected to increase utilization in the aerospace, nuclear and chemical industries. In dissimilar bonding, it is important to control the formation of intermetallic compounds that are detrimental to mechanical properties at bonding interface.
In this study, we report the microstructure and mechanical property of Ti-6Al-4V/STS 304 diffusion bonded joints using multiple interlayers such as V, Cu and Ag, which are introduced to control the formation of intermetallic compounds. Microstructural characterization was carried out by scanning electron microscope (SEM) with energy dispersive spectroscopy (EDS). Mechanical properties of the joints were measured using tensile test at room temperature with a strain rate of 8.4x10-4s-1. The surface of fractured specimen was observed by SEM. |
