Abstract Scope |
Despite over 100 years of study, liquid metal embrittlement (LME) is still poorly understood on a mechanistic level. This is in part due to the existence of multiple apparent mechanisms, sometimes competing within a single system. The aluminum gallium system is a classic example of LME, characterized by penetration of grain boundaries resulting in a near complete loss of mechanical properties. The addition of indium to the gallium liquid results in rapid oxidation and disintegration of the aluminum substrate when exposed to ambient atmosphere. By altering ambient humidity and Ga-In alloy composition, an apparent cooperative effect between corrosion and grain boundary penetration is observed. This work furthers the understanding of the role of corrosion in complex liquid metal embrittlement systems. |
