In the Fe 49.5 Mn 30 Co 10 Cr 10 C 0.5 (at.%) interstitial HEA (iHEA), the introduction of interstitial C adjusts SFE of the alloy to the critical value that triggers the TWIP effect, while also maintaining a significant contribution from the …
The conventional interstitial alloys are metal hydrides, 20 carbides, 21 borides 22 and nitrides, 23 among others. These light elements, from the first period of the p-block and below, often have small atomic radii and dominant s–p orbitals, and often occupy the largest available interstitial site: the octahedral hole in face-centre-cubic ...
The effects of interstitial alloying on the mechanical and diffusive properties of compositionally complex alloys (CCAs), including high-entropy alloys (HEAs), are reviewed.
In addition to the influence of nanoprecipitation-induced heterogeneous structures, the intrinsic hardness of the nanoprecipitates significantly enhances the wear resistance of metallic alloys [27].Introducing interstitial elements, particularly C and N, has been identified as an effective and economical approach to generate nanoprecipitates such as M 23 C 6 and Cr 2 N …
On the one hand, the interstitial atoms enter the lattice gap of the matrix and improve the strength of the alloy through interstitial solution strengthening; On the other hand, it combines with alloy elements to form the second phase precipitation, which improves the mechanical properties of the alloy through fine grain strengthening and ...
The effects of interstitial alloying on the mechanical and diffusive properties of compositionally complex alloys (CCAs), including high-entropy alloys (HEAs), are reviewed. The solubility of interstitial elements in CCAs can be extraordinarily high, a feature corroborated by ab initio density functional theory simulations.
An interstitial alloy is a type of alloy where the atoms of one element fill in the gaps or 'interstices' in the crystal lattice of another metal.

Interstitial alloys are a type of metallic alloy where the atoms of one element fill in the gaps or interstices between the atoms of another.
In this article, we review the effects of interstitial alloying in CCAs, including also their solubilities and diffusive properties.
An interstitial alloy is composed of atoms with vastly different radii. The larger atoms are arranged in an orderly lattice and the smaller atoms occupy the interstices or spaces between the larger atoms. Steel, composed of iron …
The effects of strain rate on mechanical properties, microstructural evolution and underlying deformation mechanisms of two kinds of interstitial CrMnFeCoNi high entropy alloys (HEAs), (CrMnFeCoNi) 99.5 C 0.5 and (CrMnFeCoNi) 99.0 C 1.0, are investigated under quasi-static and dynamic tension.Dynamic loading is carried out via a split Hopkinson tension bar …
INTERSTITIAL ALLOYS* Reviewed byK. E. Mironov Owing to the use of rare elements in Science and engineering, a large number of studies has appeared, dealing with the formation of interstitial alloys and compounds. The book is termed Interstitial Alloys be- cause it explains the nature of the appearance of new phases: small nonmetal atoms such as ...
An alloy is a mixture of metals or a mixture of metals plus some other elements. There are two main types of alloys as substitutional alloys and interstitial alloys. When a molten metal is used in the production of alloys, the size of the atoms will determine the type that is going to be formed. If the atoms of the metals have rel…
ZrNiSn half-Heusler (HH) alloy has an interpenetrating face-centered-cubic crystal structure with four vacant positions in the unit cell that could accommodate foreign elements, playing an imperative role in the optimization of electronic transport by tuning the band structure and band gap, as well as reducing the phonon transport by interstitial point defect scattering. …

Interstitial oxygen acts as an electronic buffer making the binding energy of other metal ele... Abstract Understanding the effect of elements' oxygen affinity is essential for comprehending high-entropy alloys' (HEAs) complete ...
Interstitial alloys form when the mixed elements in the alloy have different atomic radii, and the smaller atoms fill in the interstitial spaces (holes) in the lattice structure of larger atoms.. Substitutional alloys form when the mixed elements in the alloy have similar atomic radii. The atoms of one element can substitute into the crystal lattice structure of the other element.
Zirconium alloy has become the preferred nuclear fuel cladding material due to a series of advantages such as small thermal neutron absorption cross-section, strong water-side corrosion resistance, high mechanical properties, excellent compatibility with uranium fuel and easy cold forming, etc., and has been widely used in light water reactors [1], [2], [3].
an example of an interstitial alloy was steel, where carbon atoms "sat" in the gaps between the iron atoms. A substitutional alloy would be something like brass, where zinc atoms would replace various copper atoms in the crystal lattice. the_diego April 4, 2015, 2:28am 8. Iron and carbon don't form an alloy. ...
Different from the MoNbTaW alloy, the Ti-Zr-Hf-Nb-Ta HEAs or MEAs exhibit low sensitivity to interstitial constituents, offering significant opportunities for mechanical properties improvement [24].For equiatomic TiZrHfNb refractory HEA, 2.0 at% oxygen addition contributes to the formation of ordered interstitial complexes [25].This special oxygen-containing …
