Grain boundary energy anisotropy: a review
WebApr 14, 2024 · The relative elongation in the vertical samples significantly exceeded that in the horizontal samples. They attributed the anisotropy in the WAAM part to the directional growth of grains along the heat flow direction leading to primary grain boundaries parallel to the direction of the specimen tensile test. WebAbstract. Abstract Energetic materials are chemical compounds or mixtures that store significant quantities of energy. In this review, we explore recent approaches to property prediction and new material synthesis. We show how the successful design of new energetic materials with tailored properties is becoming a practical reality.
