Abstract
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/SUS304/Mo/Al2O3 formed with Ticusil and Cu80Ti20 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 (=50 Hz) at room temperature. The strength characteristics of the joints of Al2O3/Al2O3 formed using Ticusil were basically the same as the strength characteristics of Al2O3. The strength characteristics of the joints of Al2O3/Mo/SUS304/Mo/Al2O3 were mainly determined by the strength characteristics of the joint of Mo/Al2O3.
