TL;DR: In this paper, a model for the change in cohesive energy of a grain boundary of a pure metal upon introduction of solute under conditions of equilibrium segregation prior to fracture is developed, and a heuristic grain boundary cohesion map is presented to delineate whether a given solute-solvent pair will exhibit weakening or strengthening of grain boundaries.

TL;DR: In this paper, the authors provide the formulas required to convert between the generalized spherical harmonics and the hyperspherical harmonics, and between the coefficients appearing in their respective expansions of the ODF.

TL;DR: In this article, a rigorous framework for the description of continuous functions on the space of grain boundary parameters is developed for investigating the functional relations between the structure and the properties of interfaces, in analogy to the way that continuous distribution functions for orientation have been used extensively in the optimization of polycrystalline microstructures.

TL;DR: In this article, an ultrasonic vibrator is incorporated into the printer to improve the printing process, e.g., by disrupting a passivation layer on the deposited material to improve interlayer bonding, and to prevent adhesion of the metallic build material to a nozzle and other printer components.

TL;DR: In this article, a quaternary W-Co-Fe-C amorphous alloy was characterized using a combination of various techniques, including X-ray diffraction, calorimetry and electron microscopy coupled with energy-dispersive Xray spectroscopy and electron energy loss analysis.
