Segregant-induced cavitation of Sn/Cu reactive interface

P. L. Liu, Jian Ku Shang

Research output: Contribution to journalArticlepeer-review


A dense population of voids was found along the interface between Cu 3Sn and Cu following prolonged aging. The voids appeared only on the Cu3Sn/Cu interface that had been covered by roughly monolayer of Bi segregant. Void formation was related to vacancy condensation after the segregant took up vacancy sinks.
