To realize multi‑material structures for a circular economy, this study develops bonding, separation, and re‑bonding technologies based on interfacial liquefaction induced by a current-induced high‑speed eutectic reaction. For Al/Fe joints, separation was confirmed to occur through eutectic liquefaction at the interface.
