An assessment on the stability of the eutectic phases in high entropy alloys

Journal of Alloys and Compounds, 2019
Abstract To overcome the limited mechanical properties of single-phase FCC/BCC high entropy alloys, a large effort is being made towards the development of eutectic composites. The eutectic/near eutectic high entropy alloys (EHEAs) with alternate lamellar phases provide an optimum balance between strength and ductility. Therefore, CoCrFeNiNbx (0.45

Design of a Seven-Component Eutectic High-Entropy Alloy

Metallurgical and Materials Transactions A, 2019
A eutectic high-entropy alloy with seven components (Fe, Ni, Cr, V, Co, Mn, and Nb) was designed via the melt route guided by CALPHAD predictions. Configurational entropy estimated for the two-phase microstructure qualifies it to be referred to as a high-entropy alloy. When the Nb content exceeded 9.7 at.

Designing eutectic high entropy alloys of CoCrFeNiNb x

Journal of Alloys and Compounds, 2016
Abstract Based on surveying the existing binary phase diagrams with eutectic points, a strategy of designing eutectic high entropy alloys (EHEAs) with desired high strength and ductility is proposed. Based on the computer-aided thermodynamic calculations, the pseudo eutectic binary alloy system of CoCrFeNiNbx (x = 0.1, 0.25, 0.5 and 0.8) was designed.

Exploring the design of eutectic or near-eutectic multicomponent alloys: From binary to high entropy alloys

Science China Technological Sciences, 2017
Eutectic and near-eutectic high entropy alloys (HEAs) have recently attracted a great deal of interest because of their promising properties, such as an excellent castability and unique combination of good ductility and high strength. However, in the absence of a phase diagram, it remains a non-trivial task to find a eutectic or near-eutectic ...
