Structure and Properties of Nanoalloys Riccardo Ferrando, in Frontiers of Nanoscience, 2016 Hexagonal close-packed (hcp) nanoparticles In the hcp lattice it is not possible to create a nanoparticle whose surface is made completely of close-packed facets. In fact, it is not possible to have more...
for example, the larger ions from the close-packed structure occupy the spaces, whereas the smaller ions occupy the voids. If the latter ions are tiny, tetrahedral gaps are occupied. Whereas octahedral spaces are occupied when the later ions are larger. The percentage of octahedral or tetrahedral...

The hexagonal close-packed (hcp) structure is a highly rare phase of high-entropy metals, however, this highly desirable structure is often attributed to increasing the hardness and ductility of the metal composition in which it is found. Of the known hcp HEAs include scandium (Sc), yttrium ...
摘要: The microstructures and properties of high-entropy alloys (HEAs) based on the face-centered cubic and body-centered cubic structures have been studied extensively in the literature, but reports on HEA关键词: Binary Phase Diagram Pair Distribution Function Transition Metal Element Pearson Symbol ...
Hexagonal close packed (HCP) Mg and Zr are being used in transportation and nuclear industries, respectively. The ductility and formability of these materials is significantly limited by the activation of prevalent deformation twinning. Twins in HCP poly
