| Abstract Scope |
Cylindrical dissimilar stainless steels (SUS316L and SUS410) with identical dimension is solid-state joined by electrically assisted pressure joining (EAPJ) technique. In joining, various electric current densities are applied to the specimen assembly under compressive plastic displacement to investigate the effect of electric current density on the joining performance. The microstructural analysis results confirm that solid-state joints without macro and micro-defects are fabricated through elemental diffusion and recrystallization during EAPJ. The results of quasi-static tensile tests show that the joint’s fracture location is strongly affected by the electric current parameters during EAPJ. Moreover, the fatigue behavior of the joints is evaluated by a P-S-N curve using two-parameter Weibull distribution. Finally, the fracture mechanism was further investigated by examining the fracture surfaces from fatigue failure. |
