In this paper, ultrasonic attenuation of engineering materials is evaluated comprehensively,
covering metals, ceramics, polymers, fiber-reinforced composites, wood, and rocks. After …

Refractory high-entropy alloys (RHEAs) are designed for high elevated-temperature
strength, with both edge and screw dislocations playing an important role for plastic …

Dislocation–obstacle interactions that resist the glide of dislocations in metals, and hence
increase the applied stress necessary for plastic deformation, are treated at the atomic scale …

As the numbers of medium-to high-entropy alloys being studied and impressive structural
properties they exhibit increase rapidly, questions regarding the role played by their …

We revisit the meaning of stacking fault energy (SFE) and the assumptions of equilibrium
dissociation of lattice dislocations in concentrated alloys. SFE is a unique value in pure …

Dislocation glide is a general deformation mode, governing the strength of metals. Via
discrete dislocation dynamics and molecular dynamics simulations, we investigate the strain …

In this work, molecular dynamics simulations are conducted to investigate the shock
responses and corresponding deformation mechanisms in single crystalline (SC) and …

Atomistic simulations of dislocation mobility reveal that body-centered cubic (BCC) high-
entropy alloys (HEAs) are distinctly different from traditional BCC metals. HEAs are …

Non-Arrhenius grain boundary migration, sometimes referred to as antithermal migration
where temperature and GB velocity values are inversely related to each other, is examined …

Dislocation motion in body centered cubic (bcc) metals displays a number of specific
features that result in a strong temperature dependence of the flow stress, and in shear …
