| Abstract Scope |
The simultaneous grain boundary penetration and atmospheric oxidation of aluminum exposed to liquid gallium alloys results in accelerated degradation and spallation failure. While the cooperative effect of these mechanisms has been studied previously, we report a phenomenon of oxidation-induced dewetting and its potential as a mechanism for protecting against embrittlement. Quantifying the effects of experimental variables such as solid and liquid phase compositions, microstructure, and atmospheric conditions on the extent of degradation provides insight into a novel method of protection against liquid metal embrittlement. The current investigation examines the penetration rate, corrosion rate, and embrittlement of aluminum following static exposure to alloys of gallium, indium, and/or tin. Additionally, the rate of atmospheric oxidation will be examined under ambient and reduced concentrations of oxygen and water vapor. |
