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…
The effect of normal stress on stacking fault energy in face-centered cubic metals
Yang Li, Yuri Mishin
Plastic deformation and fracture of FCC metals involve the formation of stable or unstable stacking faults (SFs) on (111) plane. Examples include dislocation cross-slip and disloca…
Line and Planar Defects with Zero Formation Free Energy: Applications of the Phase Rule toward Ripening-Immune Microstructures
Ju Li, Yuri Mishin
Extended one- and two-dimensional defects in crystalline materials are usually metastable. The thermodynamic ground state of the material is presumed to be defect-free. Here, we in…
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…
Atomistic modeling of the structure and diffusion processes at Al(110)/Si(001) interphase boundaries obtained by vapor deposition
Yang Li, Yuri Mishin
We report on molecular dynamics simulations of the atomic structure and diffusion processes at Al(110)/Si(001) interphase boundary created by simulated vapor deposition of Al(Si) a…
Atomistic modeling of diffusion processes at Al(Si)/Si(111) interphase boundaries obtained by vapor deposition
Yang Li, Raj K. Koju, Yuri Mishin
Molecular dynamics and parallel-replica dynamics simulations are applied to investigate the atomic structures and diffusion processes at {\text{Al}\{111\}}\parallel{\text{Si}}\{111…
