The transition joints thus formed were characterized in the optical and scanning electron microscopes. The inter-diffusion of the chemical species across the diffusion interfaces were evaluated by electron probe microanalysis. TiNi3, TiNi and Ti2Ni are formed at the nickel-titanium (Ni-Ti) interface; however, the stainless steel-nickel (SS-Ni) diffusion interface is free from intermetallic compounds up to 850°C temperature. At 900°C, the Ni-Ti interface exhibits the presence of α-β Ti discrete islands in the matrix of Ti2Ni and λ+χ+α-Fe, λ+FeTi and λ+FeTi+β-Ti phase mixtures occur at the SS-Ni interface. The occurrence of different intermetallics are confirmed by the x-ray diffraction technique. The maximum tensile strength of ∼276MPa and shear strength of ∼209MPa along with 7.3% elongation were obtained for the diffusion couple processed at 850°C. At the 900°C joining temperature, the formation of Fe-Ti base intermetallics reduces the bond strength. Evaluation of the fracture surfaces using scanning electron microscopy and energy dispersive spectroscopy demonstrates that failure takes place through Ni-Ti interface up to 850°C and through the SS-Ni interface of the joint when processed at 900°C.
