The Spectral Model of Grain Boundary Solute Segregation
The segregation of solute atoms at grain boundaries (GBs) can profoundly impact the structural properties of metallic alloys, and induce effects that range from strengthening to embrittlement. And, as such, the control of solute segregation is emerging as an alloy design tool, uses of which include …

Mean-Field Parameter Study of Radiation-Induced Segregation in a Binary Metal Alloy
… system is measured by assessing the degree of segregation that occurs at the grain boundary (GB) in the center of the one-dimensional simulation box. This mean-field method was developed using rate theory equations to observe the diffusion of defects and solute atoms in the binary BCC alloy …

Polycrystalline Grain Boundary Solute Segregation at Finite Sizes and Temperatures
… alloys. With this concept, solute segregation at grain boundaries can be employed as a defect design tool to stabilize such systems against coarsening. However, the understanding and availability of grain boundary data are still limited for polycrystals that contain a profuse …

Transmission electron microscopy analysis of novel iii-v nanostructures with sb and bi for optoelectronic applications
… innovation towards a more sustainable and energy-efficient future. III-V dilute antimony and dilute bismuth semiconductor materials have been proposed for the fabrication of such devices due to their excellent properties such as tuneable bandgap, high electron mobility and low exciton …

Effect of microstructural constituents on hydrogen diffusion in multiphase alloys
… density of defects along with their associated segregation energy for hydrogen (commonly called trapping or binding energy) the effective diffusivity can be estimated, which is in turn correlated to the embrittlement susceptibility. Attempts to model hydrogen interaction with defects at …
