Current development of body-centered cubic high-entropy alloys for nuclear applications

High-entropy alloys greatly expand the alloy design range and offer new possibilities for improving material performance. Based on the worldwide research efforts in the last decade, the excellent

High-Entropy Alloys for Advanced Nuclear Applications

It is found that the understanding of the irradiation responses of HEAs remains in its infancy, and much work is needed in order for the knowledge of any single HEA system to match the authors' understanding of conventional alloys such as austenitic steels.

High-entropy ceramics: Present status, challenges, and a look forward

High-entropy ceramics (HECs) are solid solutions of inorganic compounds with one or more Wyckoff sites shared by equal or near-equal atomic ratios of multi-principal elements. Although in the infant

Recent Advances in Additive Manufacturing of High Entropy Alloys and Their Nuclear and Wear-Resistant Applications

Alloying has been very common practice in materials engineering to fabricate metals of desirable properties for specific applications. Traditionally, a small amount of the desired material is added

Microstructure and Mechanical Properties of Ni-Based Complex Concentrated Alloys under Radiation Environment

The rapid development of fusion-reactor technology calls for excellent anti-irradiation materials. Complex concentrated alloy (CCA) is a newly proposed alloy concept which is a promising candidate of

High entropy alloy synthesis, characterisation, manufacturing & potential applications: a review

ABSTRACT High entropy alloys (HEAs) are an emerging class of engineering materials with excellent mechanical, thermal, chemical and electrical properties due to constituent alloying elements and type



Irradiation Resistance of Multicomponent Alloys

High-entropy alloys (HEAs) are characterized not only by high values of entropy but also by high atomic-level stresses originating from mixing of elements with different atomic sizes. Particle

High-Entropy Alloys: A Critical Review

High-entropy alloys (HEAs) are alloys with five or more principal elements. Due to the distinct design concept, these alloys often exhibit unusual properties. Thus, there has been significant

High temperature, low neutron cross-section high-entropy alloys in the Nb-Ti-V-Zr system

Irradiation Resistance in AlxCoCrFeNi High Entropy Alloys

The irradiation behavior of AlxCoCrFeNi (x = 0.1, 0.75, and 1.5) high entropy alloys was studied under 3 MeV Au-ions irradiation. The microstructural change and volume swelling due to irradiation

Mechanism of Radiation Damage Reduction in Equiatomic Multicomponent Single Phase Alloys.

A combination of experimental and modeling efforts reveals a substantial reduction of damage accumulation under prolonged irradiation in single-phase NiFe and NiCoCr alloys compared to elemental Ni, explained by reduced dislocation mobility, which leads to slower growth of large dislocation structures.

High-Entropy Alloys – A New Era of Exploitation

A high-entropy alloy (HEA) has been defined by us to have at least five principal elements, each of which has an atomic concentration between 5% and 35%. In the exploration on this new alloy field,
