In situ measurement of dihedral angles at liquid grain boundary inclusions.
This work describes experimental aspects of the measurement of relative interfacial energies from the equilibrium dihedral angles of small liquid inclusions or precipitates at interfaces in solids using in situ transmission electron microscopy. We demonstrate how limitations such as faceting, free surfaces, and projection errors can be handled to minimize experimental errors.
