Abstract
Low cycle fatigue tests were performed at room temperature for 316 stainless steel (316SS), alumina dispersion strengthened copper (DS Cu) and 316SS-DS Cu diffusion bonded joints. Plastic strain distribution of joint specimens during the fatigue was measured to estimate deformation of the joint specimens. Furthermore, microstructure of diffusion zone of the joints and fracture surface of the fatigue specimens were examined with scanning and transmission electron microscopes. The fatigue life of the joints was lower than that of DS Cu. The joint specimens fractured at the DS Cu near the interface in the case of small strain range fatigue tests. Intermetallic compounds and recrystallization were found near the interface in DS Cu. It is considered that these intermetallic compounds and recrystallization affected the low cycle fatigue strength for small strain range fatigue tests. For large strain range fatigue tests, however, fracture point was in the DS Cu 6-7mm apart from the interface, at which the maximum plastic strain occurred. It is assumed that the 316SS restrained the deformation of DS Cu near the interface for large strain range fatigue. (author).
