A GRACE Interatomic Potential for W--Ta Systems: Application to Ta Segregation and Pinning of Shear-Coupled Grain-Boundary Migration
Omar Hussein, Laurent Capolungo, Danny Perez
Tungsten-tantalum alloys are promising plasma-facing materials for fusion reactors, but simulations of their coupled defect, mechanical, and microstructural evolution require an in…
Ductility and Brittle Fracture of Tungsten by Disconnection Pile-up on Twin Boundaries
Omar Hussein, Nicolas Bertin, Jakub Veverka +5
Refractory body-centered cubic (BCC) metals and alloys are of extraordinary importance in modern technological and structural applications. However, their wider adoption in science…
Self-pinning mechanism for grain boundary stabilization
Omar Hussein, Yuri Mishin
Previous research focused on two different mechanisms of microstructure stabilization in alloys: thermodynamic stabilization by reducing the grain boundary (GB) free energy and kin…
A model of full thermodynamic stabilization of nanocrystalline alloys
Omar Hussein, Yuri Mishin
We propose a model of a polycrystalline alloy combining the Potts model for grain orientations with a lattice-gas model for solute thermodynamics and diffusion. The alloy evolution…
A model of thermodynamic stabilization of nanocrystalline grain boundaries in alloy systems
Omar Hussein, Yuri Mishin
Nanocrystalline (NC) materials are intrinsically unstable against grain growth. Significant research efforts have been dedicated to suppressing the grain growth by solute segregati…
