TL;DR: In this paper, a semi-automated method has been used to measure all five macroscopically observable parameters of 4.1×10 6 boundary plane segments making up 5.4 mm 2 of boundary area in a hot-pressed magnesia polycrystal.

TL;DR: In this article, the authors measured all five macroscopically observable degrees of freedom of 41 × 106 boundary plane segments making up 52 × 106μm2 of grain boundary interface area in a magnesia polycrystal and demonstrated that not all grain boundary configurations occur with the same frequency and that the relative free energies of the different interfacial configurations influence the population distribution.

TL;DR: In this article, a numerical method for reconstructing the grain boundary energy distribution over the complete space of macroscopic boundary parameters is presented, based on the analysis of the dihedral angles between homophase grain boundaries of polycrystalline triple junctions.

TL;DR: In this article, a finite series of symmetrized spherical harmonics has been used to approximate the misorientation dependence of the relative grain boundary energy, and best fit coefficients for this series were determined by assuming that the interfacial tensions at each triple junction are balanced.

TL;DR: A new experimental approach to the quantitative characterization of polycrystalline microstructure by scanning electron microscopy by combining automated electron backscattering diffraction with conventional scanning contrast imaging and with calibrated serial sectioning, which recovers precision estimates of the 3D idealized aggregate function G(x).
