In general, structural integrity depends on material performance under cyclic loading. It is therefore very important to characterize the fatigue strength characteristics of ceramic/metal joints for wide use in structural applications of engineering ceramics. In this work, in order to clarify the strength characteristics of alumina joints, static strength and cyclic fatigue tests were carried out for joints of Al₂O₃/Al₂O₃ and Al₂O₃/Mo/SUS 304/Mo/Al₂O₃ formed with Ticusil and Cu₈₀ Ti₂₀ fillers in vacuum. Static tests were conducted at room temperature and elevated temperature. Fatigue tests were conducted at constant stress ratio R(=0.1) and constant frequency f(=50Hz) at room temperature. The strength characteristics of the joints of Al₂O₃/Al₂O₃ formed using Ticusil were similar to the strength characteristics of Al₂O₃. The strength characteristics of the joints of Al₂O₃/Mo/SUS 304/Mo/Al₂O₃ were mainly determined by those of the joint of Mo/Al₂O₃.
