Diffusion bonding between commercially pure titanium and 304 stainless steel was carried out at a temperature of 950 °C for 30–120 min under uniaxial load in a vacuum. The diffusion bonds were characterized by optical and scanning electron microscopy. The diffusion zone contained different reaction bands and their chemical composition was determined using energy dispersive X-ray spectroscopy. The concentration of chemical species indicated the presence of σ, λ, χ, FeTi, β-Ti and Fe2Ti4O phases in the reaction zone and their existence was confirmed by X-ray diffraction. A maximum bond strength of 71% of that of titanium along with 5.8% ductility were obtained for the diffusion couple processed for 30 min due to formation of finer size intermetallics. A rise in joining time increases void generation and growth of intermetallic compounds, which are responsible for a drastic fall in the strength value.
