Atomistic Modeling of Defect Energetics and Kinetics at Interfaces and Surfaces in Metals and Alloys
… cohesive strength, and the controversial sluggish diffusion in both the bulk and grain boundaries of high entropy alloys. First, an analytical formula is derived, which can predict the surface energy of any arbitrary (h k l) crystallographic orientation in both body-centered-cubic (BCC) …

Machine-Learning Assisted Atomic Simulations of Defect Dynamics in Multicomponent Concentrated Alloys
This dissertation investigates the complex defect diffusion behaviors in concentrated solid solution alloys (CSAs) including high-entropy alloys (HEAs), which are critical for understanding their exceptional mechanical and radiation-resistant properties. Through a combination of multiple …

Insights on the synthesis, properties, and performance of high-nickel layered oxide cathodes
… limiting single-crystal performance is poor diffusion kinetics. However, the elimination of intergranular boundaries elicits surprising phase transition behavior; despite sluggish diffusion, nucleation-controlled transformations are maintained to much higher current draws due to the larger …

The effects of irradiation on the creep and hardening behavior of crystalline and amorphous materials
… regime is measured to be ~ 0.7 eV. The sluggish diffusion behavior often cited as a novel feature of these alloys has very limited effect on the observed creep behavior. 3) A low (200 keV or 80 keV) energy electron beam is used to induce creep in SiO2, Fe79B16Si5, CuTi and CuTa metallic …

Titanite zoning and magma mixing
… et al. 2000). It is also characterised by very sluggish diffusion of these elements, and as such it has the ability to resist most sub-solidus alteration. These characteristics make titanite a prime candidate for the ability to preserve a record of the petrogenetic processes which formed the …
