A low-density high-entropy dual-phase alloy with hierarchical structure and exceptional specific yield strength

Yasong Li et al.

Summary: A high-entropy dual-phase AlTiVCoNi alloy with a low density and hierarchical structure has been developed. The alloy exhibits phase stability due to the semi-coherent interface of the L2(1) and BCC phases, and shows exceptional compressive strength at both room and high temperatures.

Effects of precipitate size and spacing on deformation-induced fcc to bcc phase transformation

Eva Zarkadoula et al.

Summary: Using molecular dynamics simulations, this study investigates the deformation-induced phase transition in an Fe-Ni alloy with and without precipitates. The results show that larger precipitates and smaller spacings hinder the phase transformation. These findings help interpret the experimental results and analyze the individual effects of precipitate size and spacing.

Abnormal hardening and amorphization in an FCC high entropy alloy under extreme uniaxial tension

Kun Jiang et al.

Summary: This study investigates the mechanical responses and microscopic observations of a face-centered cubic high entropy alloy under different loading conditions. The results reveal a transition of plasticity mechanisms as the strain increases, including twinning, detwinning-induced localization, nanoscale phase transformation, and amorphization. The hindrance of twin boundaries to localized band propagation and the emission of more dislocations from body-centered cubic phases result in a second rise in hardening. The plasticity increases during the crystal to amorphization transition, possibly due to severe lattice distortion in areas with super-dense dislocations. Molecular dynamic simulations provide a deeper understanding of the phase transition mechanisms.

Molecular dynamics simulations to quantify the interaction of a rigid and impenetrable precipitate with an edge dislocation in Cu

K. Tsugawa et al.

Summary: This study introduced a method to simulate the interaction between precipitates and dislocations using molecular dynamics simulation. The research found that when a dislocation overcomes a precipitate, an Orowan loop is formed along the outer circumference of the precipitate, resulting in greater hardening compared to voids of the same size.

Atomic-scale insight into interaction mechanism between extended dislocation and amorphous phase in high entropy alloys

L. Han et al.

Summary: The effect of amorphous nanopillar size, amorphous nanopillar spacing, and temperature on the behavior of extended dislocations overcoming amorphous obstacles in high-entropy alloys (HEAs) was investigated using molecular dynamics simulation. The results showed that the introduction of amorphous nanopillars can improve the strength of HEAs, with larger nanopillar sizes leading to a more significant strengthening effect.

A first-principles-based high fidelity, high throughput approach for the design of high entropy alloys

V Sorkin et al.

Summary: This study presents a high fidelity, high throughput method for fast screening of high entropy alloys. By using the preselected small set of ordered structures method, the formation energies and mass densities of a large number of compositions were accurately calculated and the most stable ones were selected for further analysis. The method was validated against experimental data and found to outperform the special quasi-random structures method in terms of efficiency.

Improved Voigt and Reuss Formulas with the Poisson Effect

Yunhua Luo

Summary: The Poisson effect, which is not considered in conventional formulas, plays an important role in regulating the elastic properties of composite materials. To consider this effect, new formulas were derived and found to exhibit greater mathematical complexity. Simulation models showed that the Poisson effect increases composite stiffness, with the magnitude of the increase depending on the contrast of phase properties.

Effect of short-range ordering and grain boundary segregation on shear deformation of CoCrFeNi high-entropy alloys with Al addition

Rita Babicheva et al.

Summary: A method combining molecular dynamics (MD) and Monte Carlo (MC) simulation was used to analyze the short-range ordering and grain boundary (GB) segregation in the bi-crystals of equiatomic CoCrFeNi and Al (8 at%)-CoCrFeNi high-entropy alloys (HEAs). The study found that the GB segregation greatly influences the deformation behavior of the alloys, with aluminum atom segregation increasing the shear yield strength.

Tensile deformation behavior of twist grain boundaries in CoCrFeMnNi high entropy alloy bicrystals

Hyunsoo Lee et al.

Summary: High entropy alloys (HEA) are materials composed of multiple elemental species in similar concentrations, allowing for tailored properties. Despite active research on the mechanical behavior of HEAs, the role of grain boundaries (GBs) in their deformation behavior remains poorly understood. Atomistic simulations show that plastic deformation in HEAs proceeds from nucleation of partial dislocations at GBs, providing insights for designing HEAs with specific properties.

Nanoprecipitate-Strengthened High-Entropy Alloys

Liyuan Liu et al.

Summary: HEAs can be tuned to a simple phase with unique alloy characteristics, such as high strength and hardness with low ductility in BCC or HCP structures, and a combination of considerable ductility, excellent corrosion and radiation resistance in FCC structures. Precipitation strengthening is an effective method to enhance the strength of HEAs by forming fine and stable nanoscale precipitates. This paper reviews the recent progress in nanoprecipitate-strengthened HEAs and highlights alloy-design strategies and control of nanoscale precipitates.
