Correlating dislocation mobility with local lattice distortion in refractory multi-principal element alloys

Bing Chen et al.

Summary: This study found that lattice distortion affects the mobility of dislocations in body-centered-cubic multi-principal element alloys. Lattice distortion influences the activation of kink nucleation and propagation for screw dislocation motion, as well as the strength of local pinning for edge dislocations. The lattice distortion can be used as an indicator to correlate with the reported brittleness of these alloys.

Design of BCC refractory multi-principal element alloys with superior mechanical properties

Weiji Lai et al.

Summary: This study identified the correlations between tensile properties and common physical parameters in BCC refractory multi-principal element alloys, providing guidelines for alloy design. Some BCC RMPEAs with excellent tensile properties were successfully designed, with high strength attributed to lattice distortion and good ductility attributed to dislocation glide.

Theory-guided design of high-strength, high-melting point, ductile, low-density, single-phase BCC high entropy alloys

Y. Rao et al.

Summary: The search for new high-temperature alloys has been accelerated with the discovery of body-centered cubic refractory High Entropy Alloys. Using recent theories and expanded thermodynamic tools, this study demonstrates a method to discover and design alloys with desired properties. The search process successfully identifies HfMoNbTaTi alloy as a satisfying candidate and further discovers new quinary and quarternary alloys with improved overall properties. This design process has the potential to explore millions of alloys with different performance requirements.

Multicomponent high-entropy Cantor alloys

B. Cantor

Summary: Multicomponent high-entropy Cantor alloys, discovered in the late 1970s, occupy a vast region of multi-component phase space and exhibit excellent mechanical properties due to high configurational entropy. The complexity of local atomic configurations and associated lattice strains in these alloys contributes to their unique characteristics and potential for further enhancement and optimization.

Different lattice distortion effects on the tensile properties of Ni-W dilute solutions and CrFeNi and CoCrFeMnNi concentrated solutions

Kuan-Hao Lin et al.

Summary: This study compared the lattice distortion effects in conventional and high-entropy alloys and found that different types of lattice distortion have significantly different effects on the tensile properties of alloys. For different types of concentrated solutions, the location and extent of lattice distortion also vary.

Role of Static Displacements in Stabilizing Body Centered Cubic High Entropy Alloys

G. D. Samolyuk et al.

Summary: The configurational entropy of high entropy alloys has little impact on stabilizing one crystal structure over another, while disorder-induced atomic displacements help stabilize specific structures. Chemical disorder in high entropy alloys provides a previously unidentified, non-entropic energy contribution to stabilize a particular crystalline ground state.

Effects of temperature on mechanical properties and deformation mechanisms of the equiatomic CrFeNi medium-entropy alloy

Mike Schneider et al.

Summary: Investigations on equiatomic CrFeNi medium-entropy alloy reveal stable face-centered cubic solid solution properties at specific temperatures. Cold-working and recrystallization processes can produce different grain sizes, showing varied mechanical properties and deformation mechanisms influenced by temperature. Analysis of deformation processes at different strains indicates a combination of dislocation glide and twinning mechanisms.

Element-resolved local lattice distortion in complex concentrated alloys: An observable signature of electronic effects

Hyun Seok Oh et al.

Summary: The study on element-resolved local lattice distortion in 3d transition-metal element CCAs reveals that ELLD is primarily dependent upon charge transfer among elements and affects properties through atomic-level pressure and orbital transition, providing a qualitative measure of effective atomic size to explain element-specific and macroscopic properties.

Elastic dipole tensors and relaxation volumes of point defects in concentrated random magnetic Fe-Cr alloys

Jan S. Wrobel et al.

Summary: The study investigates point defects in body-centred cubic Fe, Cr, and concentrated random magnetic Fe-Cr alloys using density functional theory and theory of elasticity. It finds significant fluctuations in elastic dipole and relaxation volume tensors of vacancies and self-interstitial atom (SIA) defects, showing a correlation between elastic relaxation volumes and magnetic moments of defects. The properties of point defects in alloys are found to differ significantly depending on the Cr content, with magnetism playing a significant role in influencing the elastic fields of defects in Fe-Cr alloys.

Experimental and theoretical evidence of charge transfer in multi-component alloys - how chemical interactions reduce atomic size mismatch

Luis Casillas-Trujillo et al.

Summary: The study combined ab initio simulations of a multi-component alloy using density functional theory (DFT) with experiments on thin films of the same material using X-ray photoelectron spectroscopy (XPS) to investigate the electronic and atomic structures. The simulations showed that charge transfer in the equimolar HfNbTiVZr multi-component alloy followed electronegativity trends, leading to reduced lattice distortions compared to traditional assumptions based on tabulated atomic radii. Experimental validation was conducted using XPS measurements, showing good agreement with the calculated DFT values and confirming a non-ideal solid solution phase for HfNbTiVZr.
