The influence of alloying on Zn liquid metal embrittlement in steels

D Scheiber, K Prabitz, L Romaner, W Ecker - Acta Materialia, 2020 - Elsevier
In this study we investigate Zn liquid metal embrittlement at Fe grain boundaries (GBs) by
employing ab initio density functional theory (DFT) simulations. We consider three different …

Grain size dependencies of intergranular solute segregation in nanocrystalline materials

N Tuchinda, CA Schuh - Acta Materialia, 2022 - Elsevier
Grain boundary segregation is of increasing importance for stabilizing nanocrystalline
alloys, and while segregation is typically modeled as a scale-independent phenomenon, at …

Grain boundary segregation predicted by quantum-accurate segregation spectra but not by classical models

M Wagih, Y Naunheim, T Lei, CA Schuh - Acta Materialia, 2024 - Elsevier
In alloys, solute segregation at grain boundaries is classically attributed to three driving
forces: a high solution enthalpy, a high size mismatch, and a high difference in interfacial …

Grain boundary solute segregation across the 5D space of crystallographic character

LH Serafin, ER Cluff, GLW Hart, ER Homer - Acta Materialia, 2025 - Elsevier
Solute segregation in materials with grain boundaries (GBs) has emerged as a popular
method to thermodynamically stabilize nanocrystalline structures. However, the impact of …

Phase-and-Defect Diagrams for Polycrystalline Grain Boundary Segregation

TP Matson - 2024 - dspace.mit.edu
Defect engineering provides access to a much larger range of material properties and is
particularly necessary when designing any high-defect density material such as …

The Spectral Model of Grain Boundary Solute Segregation

MMAH Wagih - 2021 - dspace.mit.edu
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 …
