Diffusion welding/bonding has been successfully used to joint dissimilar metals widely. In this study, pure Ti andAISI430ferriticstainlesssteelplateswerejoinedthrough diffusionweldingusingaNiinterlayeratvarioustemperatures (800, 825, 850 and 875 °C), holding times (15, 30, 60 and 120 min) and under a constant pressure (3 MPa) under argon shielding media. The welded joints were subjected to tensileshear tests and hardness tests in order to determine their interfacial strength. In addition, microstructural properties of the joined interface were examined using optical and scanning electron microscope (SEM). The tensile-shear test results showed that the fractures occurred mostly in the interface of the Ni ferriticstainlesssteelwebatlowertemperatures.Itwas seen from the hardness results that the highest hardness value was obtained for the titanium side and the hardness values increased with increasing welding temperature and holding time.SEM/EDSexaminationsshowedthatthediffusedatoms and diffusion distance increased depending on the increasing temperature and holding time.
