Abstract Scope |
The most often considered interaction between a liquid metal and solid metal is grain boundary wetting leading to catastrophic degradation of the solid's mechanical properties, usually termed liquid metal embrittlement. However, there are numerous other liquid-solid interactions to consider, including embrittlement of single crystals, variable grain boundary penetration kinetics, and liquid-metal-mediated recrystallization. This study utilizes advanced electron microscopy techniques including electron backscatter diffraction to examine the mechanisms underlying these poorly studied phenomena. This is paired with a machine learning model to test the hypothesis that the umbrella term "liquid metal embrittlement" is actually composed of multiple separable mechanisms. |
