A new infinite solid solution strategy to design eutectic high entropy alloys with B2 and BCC structure

TL;DR: In this article, the authors reported the use of composition design, that is the addition of Ni element into a base alloy of AlCoCrFeTi0.5Ni2.5 HEA, to obtain the body-centered cubic (BCC)/face-center cubic (FCC) dual-phase structure, for avoiding the strength-plasticity trade-off.

TL;DR: In this article , a method to design EHEAs by determining the formation of single-phase solid solution and calculating solidification paths using JMatPro software was proposed, where two phases (eutectic) solidified simultaneously when no inflexion point appears on the cooling curves of constituent phases.

TL;DR: Researchers design and prepare FCC-based triple-phase eutectic high-entropy alloys with multi-scale microstructure, exhibiting promising mechanical properties, and propose a pseudo-ternary strategy for designing multiphase eutectic structures in high-entropy alloys.

TL;DR: In this paper , a modified simple mixture method was proposed to systematically design EHEAs containing more than five elements in CoCrFeNi-M (Nb, Ta, Zr, and Hf) to further expand the compositional space.

TL;DR: In this paper, it was shown that the confusion principle does not apply, and other factors are more important in promoting glass formation of late transition metal rich multicomponent alloys.

TL;DR: In this article, the factors of the atomic size difference Delta and the enthalpy of mixing ΔH mιx of the multi-component alloys were summarized from the literatures.

TL;DR: In this article, two refractory high-entropy alloys with nearequiatomic concentrations, WNB-Mo-Ta and WBMCV, were produced by vacuum arc melting and the lattice parameters were determined with high-energy X-ray diffraction using a scattering vector length range from 0.7 to 20A−1.

TL;DR: In this paper, the relationship between phase stability and physicochemical/thermodynamic properties of alloying components in high entropy alloys was studied systematically and the mixing enthalpy was found to be the key factor controlling the formation of solid solutions or compounds.
