High-entropy alloys: a review of mechanical properties and deformation mechanisms at cryogenic temperatures

Xuefeng Gao et al.

Summary: High-entropy alloys (HEAs) have great potential in cryogenic temperature structural materials due to their unique composition design and excellent properties. This paper reviews the deformation behavior and microstructural evolution of HEAs at cryogenic temperature, as well as the research and development of tensile, compressive, and fracture toughness. It also discusses the challenges and future trends of HEAs at cryogenic temperature.

High throughput synthesis enabled exploration of CoCrFeNi-based high entropy alloys

L. Zhao et al.

Summary: By employing the High-Throughput Hot-Isostatic-Pressing based Micro-Synthesis Approach (HT-HIP-MSA), 85 combinatorial alloys in a 13-principal element alloying space were synthesized and characterized, and their composition-structure-property relationships were experimentally and computationally analyzed. The results revealed that the addition of Mn extended the solubility of the alloys, most quinary and senary alloys exhibited destabilizing behavior, and the alloys showed distinctive solid-solution-strengthening effects.

Phase-selective recrystallization makes eutectic high-entropy alloys ultra-ductile

Qingfeng Wu et al.

Summary: This study proposes the concept of phase-selective recrystallization to improve the ductility and strength of eutectic alloys. By manipulating the strain partitioning behavior of the duplex phases, the resulting microstructure fully releases the strain hardening capacity and achieves high ductility. This concept is applicable to various duplex alloys and opens new frontiers for traditional eutectic alloys as high-strength metallic materials.

Microstructure evolution and formation mechanism of CoCrCu1.2FeNi high entropy alloy during the whole process of semi-solid billet preparation

Jufu Jiang et al.

Summary: Dual face-centered cubic (FCC) CoCrCu1.2FeNi semi-solid billets were prepared by semisolid isothermal treatment of wrought high entropy alloy (HEA) (SSITWH) method. The microstructure evolution in the whole process of billets preparation was systematically investigated. The effect of temperature and soaking time on semi-solid microstructure was studied, and the alloy had low coarsening coefficients.

Effects of deformation and annealing on the microstructures and properties of a nonequiatomic Co29Cr29Fe29Ni12.5W0.5 high-entropy alloy

Chengbin Wei et al.

Summary: The high-entropy alloys Co29Cr29Fe29Ni12.5W0.5 prepared by vacuum induction melting and mechanical processing exhibited outstanding mechanical properties with a yield strength of 1.13 GPa and fracture elongation of 24.3% after annealing at 725 degrees C. The addition of W element and ultrafine grain structure were attributed to the excellent mechanical properties observed in the alloy.

Gradient nanotwinned CrCoNi medium-entropy alloy with strength-ductility synergy

Shuqing Yuan et al.

Summary: A high-strain rate ultra-precision machining technology named single point cubic boron nitride turning was developed to fabricate gradient nanotwinned CrCoNi medium entropy alloy layer. The refinement process from core to surface was governed by size-dependent twinning mechanisms, resulting in significantly enhanced yield strength and well-retained ductility. The machining process provided sufficient equivalent stress to activate twinning partials for forming the gradient nanotwinned structure.
