摘要: In the present study, diffusion bonding of titanium and micro-duplex stainless steel was investigated in vacuum. Diffusion interfaces were characterized using light microscopy, scanning electron microscopy X-ray diffraction technique. The inter-diffusion chemical species across evaluated by probe microanalysis (EPMA). maximum tensile strength ~97% shear ~80% those Ti along with 6.9% elongation obtained for couple processed at 900°C joining temperature. Fracture surface observation SEM EDS demonstrates that, failure takes place through β-Ti phase when up to 850°C, however, λ+FeTi+β-Ti couples above
