Joining of different materials, which have different physical and mechanical characteristics, is always challenging task. One method, by which very good results can be attained, is diffusion bonding. The main aim of writing this diploma thesis is to figure out the suitable metallic interlayer with negligible deformation and then achieve good ductility by adopting diffusion welding technology between titanium grade 2 and high-alloy austenitic AISI 316L steel. Fundamental theory of diffusion, its bonding mechanism, effect of distinct variables and real world examples were discussed in the theoretical part. Experiments were executed on Gleeble 3500 thermal-mechanical simulator machine. Weldments were subsequently evaluated in light of mechanical properties by carrying out micro-hardness test and also analyzed metallography by using scanning electron microscope (SEM) and optical microscope (OM).
