In situ investigation of liquid Ga penetration in Al bicrystal grain boundaries: grain boundary wetting or liquid metal embrittlement?
TL;DR: The phenomenon of grain boundary penetration of liquid Ga along grain boundaries (GB) of Al bicrystals is investigated by synchrotron radiation X-ray microradiography as discussed by the authors.

Discontinuous penetration of liquid Ga into grain boundaries of Al polycrystals
TL;DR: In this paper, the process of grain boundary penetration of liquid Ga in Al polycrystals is characterized by synchrotron radiation X-ray microradiography, which allows for non-destructive in situ characterization of dynamic processes in the bulk of millimetric size Al samples.

Direct Evidence of Nanometric Invasionlike Grain Boundary Penetration in the Al/Ga System
TL;DR: The first in situ results of deformation during grain boundary penetration in the A(1)/Ga system are reported, obtained with a novel, nondestructive hard x-ray synchrotron projection microscopy technique.

In situ investigation of Al bicrystal embrittlement by liquid Ga using synchrotron imaging
TL;DR: In this article, the penetration behavior of liquid Ga along two different types of symmetrical tilt Al bicrystals is analyzed as a function of tensile load applied normal to the boundary plane by means of synchrotron radiation X-ray micro-radiography.
