Abstract: This work investigates the effect of continuous CuAlO2 interfacial reaction product layers on the strength of eutectic bonded copper–alumina interfaces. The fracture resistance was characterized for interfaces produced by eutectic bonding with and without continuous CuAlO2 interlayers. Results show that continuous CuAlO2 layers can weaken the overall Cu/Al2O3 bond.
