In a previous study, the tensile strength of dissimilar friction welded joints that was composed between commercially pure Al (AA1070) and low carbon steel (LCS) decreased with increasing forge pressure. This result was not applicable to the gener...
The joint strength and its improvement of AA5083 Al alloy joints fabricated by friction stud welding method were investigated. The diameter of the work and stud side specimens were 32.0 mm and 12.8 mm, respectively, and those were friction welded....
Thermal stresses are repeatedly applied to members due to temperature cycle of heating and cooling. Then, the members often fail due to the repeated stresses as a result of inelastic behaviors and fatigue deformations. This study is concerned with...
The joining phenomena during the friction process of pure titanium (Ti) and pure copper (OFC) friction welding was investigated. When the joint was made at a friction pressure of 60MPa or lower, the OFC side was deformed from both weld faying surf...
The impulsive riveting method can join the sheets without drilling as well as disjoin easily the jointed sheets. The joints made by the method have high joint strength and the deformation of the joints is also small. However, the equipment for the...
In order to predict the cyclic fatigue life of alumina ceramics, a new method was proposed. First, to monitor the small crack growth behavior during static fatigue, a thin metal film method was proposed. Second, based on the crack growth data, cra...
This paper describes the analysis method of friction torque and weld interface temperature during friction process by FEM. The joining model of the wear and seizure stages was constructed from the joining phenomena that were obtained by the experi...
