WebMay 18, 2024 · Hafnium-based alloys of two similar compositions were prepared by arc melting and suction casting to produce 6-mm-diameter cast rods of an amorphous alloy and a crystalline one. The selected compositions were Hf 48 Cu 29 Ni 10 Al 13 (amorphous) and Hf 58 Cu 20 Ni 16 Ti 6 (crystalline), as confirmed by X-ray diffraction. The hardness … WebApr 24, 2003 · For our purposes, all metals and alloys are crystalline solids, although some metals have been formed in the lab without crystalline structure. And most metals assume one of three different lattice, or crystalline, structures as they form: body-centered cubic (BCC), face-centered cubic (FCC), or hexagonal close-packed (HCP).
WebOct 12, 2024 · Addition of refractory metals with large atoms seems to be useful for obtaining good soft magnetic properties. However, with similar properties, Tungsten (W) … WebAn alloy might also be a crystal with a metallic compound at each lattice point. In addition, alloys may be composed of secondary crystals imbedded in a primary polycrystalline matrix. This type of alloy is called a composite (although the term "composite" does not necessarily imply that the component materials are metals).
WebCrystalline alloys are designated macrocrystalline, microcrystalline, or nanocrystalline. Amorphous alloys with local order similar to crystalline counterparts are known as amorphous I alloys, whereas amorphous alloys with noncrystalline local order belong to the amorphous II type. Table 6. WebAug 24, 2012 · When the grain, or crystallite, size in a polycrystal is reduced below about 100 nm, grain boundary or interface physics begin to dominate over conventional crystal physics (1–4).A variety of interesting and useful properties emerge in such nanostructured materials (5–10), but their large volume fraction of grain boundaries also comes with an …
WebDec 10, 2024 · Researchers have found a new way to predict the properties of metal alloys based on reactions at the boundaries between the crystalline grains of the primary metal. In this image, the colored dots indicate the likelihood that atoms will collect along these boundaries rather than penetrating through. Credits Image courtesy of the researchers
