| Abstract Scope |
Bulk solid-state joints of various combinations of dissimilar metal alloys are successfully fabricated by electrically assisted pressure joining (EAPJ) technique. The quality of joints was evaluated by microstructural analysis and mechanical testing. 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 base metal fracture rather than interface fracture can be achieved by adjusting input parameters. Moreover, for the material combination of SUS316L and SUS410, the fatigue behavior of the joints is evaluated by a P-S-N curve using two-parameter Weibull distribution. Finally, the results of experiments with combinations of non-ferrous metal alloys confirm that the concept of EAPJ is also applicable to non-ferrous metal alloys, including copper or aluminum alloys. The present study demonstrates that EAPJ is an efficient method in the bulk joining of dissimilar metal alloys combinations. |
