FeCrNiMnAl High-Entropy Alloy (HEA) Spherical Powder

Product Information

High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements. Prior to the synthesis of these substances, typical metal alloys comprised one or two major components with smaller amounts of other elements. For example, additional elements can be added to iron to improve its properties, thereby creating an iron-based alloy, but typically in fairly low proportions, such as the proportions of carbon, manganese, and others in various steels. Hence, high-entropy alloys are a novel class of materials. The term "high-entropy alloys" was coined by Taiwanese scientist Jien-Wei Yeh because the entropy increase of mixing is substantially higher when there is a larger number of elements in the mix, and their proportions are more nearly equal. Some alternative names, such as multi-component alloys, compositionally complex alloys and multi-principal-element alloys are also suggested by other researchers. Alloys that have been maturely melted include W, Ta, Mo, Nb, V, Cr, Zr, Ti, Hf, and other metals with equal atomic ratios and non-equal atomic ratios in high-entropy alloys. Ordinary components of Co, Cr, Fe, Ni, Cu, Al can be melted and cut by high entropy alloy of various systems according to the customer requirements of components, and processe These alloys are currently the focus of significant attention in materials science and engineering because they have potentially desirable properties.

High-Entropy Alloys Manufacture

High-entropy alloys are difficult to manufacture using extant techniques ， and typically require both expensive materials and specialty processing techniques. High-entropy alloys are mostly produced using methods that depend on the metals phase – if the metals are combined while in a liquid, solid, or gas state. Most HEAs have been produced using liquid-phase methods include arc melting, induction melting, and Bridgman solidification. Solid-state processing is generally done by mechanical alloying using a high-energy ball mill. This method produces powders that can then be processed using conventional powder metallurgy methods or spark plasma sintering. This method allows for alloys to be produced that would be difficult or impossible to produce using casting, such as AlLiMgScTi. Gas-phase processing includes processes such as sputtering or molecular beam epitaxy (MBE), which can be used to carefully control different elemental compositions to get high-entropy metallic or ceramic films. Additive manufacturing, can produce alloys with a different microstructure, potentially increasing strength (to 1.3 gigapascals) as well as increasing ductility. Other techniques include thermal spray, laser cladding, and electrodeposition.
