Lattice parameter for hcp
WebCobalt base (Co-Cr-Mo-C) alloys are known to exhibit two crystal structures, namely, face-centered-cubic (fcc) and hexagonal-close-packed (hcp). Accordingly, in this work, fcc and hcp lattice constants were measured at room and elevated temperatures in a Co-27Cr-5Mo-0.05C alloy using “in-situ” X-ray diffraction techniques. It was found that the lattice … Web8 apr. 2024 · Hexagonal close packing, or hcp in short, is one of the two lattice structures which are able to achieve the highest packing density of ~74%, the other being face …
