In this study, the effects of the bonding conditions and the postheat treatment on the bondability of the joints of molybdenum to titanium have been investigated. Results obtained are summarized as follows ; 1) In case of the joint of molybdenum to titanium, the diffusion layers formed on bonded zone were both β phase and α+β phase. Kirkendall effect was observed at the bond interface between molybdenum and titanium, and the voids were formed in diffusion layer. 2) The joint strength of the joint of molybdenum to titanium depended on the bonding temperature and the maximum joint strength of 440 MPa was obtained at 850℃ for the bonding time of 1 ks and 1.8 ks, and tension fracture occurred in titanium base metal. However, the joint strength decreased as the bonding temperature became higher. 3) When joints having the maximum joint strength were heated at 700℃, the joint strength was not affected by the heating time up to 72 ks. However, it decreased with the increase of holding time at 900℃ and 1000℃. 4) Rotating bending fatigue limits of the joints of Mo/Ti, TZM/Ti, Mo/Ti-6Al-4V and TZM/Ti-6Al-4V were the value of 40%〜50% of each joint strength.
