Development of interatomic potential appropriate for simulation of dislocation migration in fcc Fe
Mikhail I. Mendelev, Valery Borovikov
Molecular dynamics (MD) simulation of dislocation migration requires semi-empirical potentials of the interatomic interaction. While there are many reliable semi-empirical potentia…
Effects of Grain Boundary Disorder on Yield Strength
Valery Borovikov, Mikhail I. Mendelev, Alexander H. King
It was recently reported that segregation of Zr to grain boundaries (GB) in nanocrystalline Cu can lead to the formation of disordered intergranular films [1,2]. In this study we e…
Effect of Ag and Zr solutes on dislocation emission from the Σ11(332)[110] symmetric tilt grain boundary in fcc Cu
Valery Borovikov, Mikhail I. Mendelev, Alexander H. King
Addition of solutes is commonly used to stabilize nanocrystalline materials against grain growth. However, segregating at grain boundaries, these solutes also affect the process of…
Solute effects on interfacial dislocation emission in nanomaterials: nucleation site competition and neutralization
Valery Borovikov, Mikhail I. Mendelev, Alexander H. King
Interfacial nucleation is the dominant process of dislocation generation during the plastic deformation of nano-crystalline materials. Solute additions intended to stabilize nano-c…
Effect of Stacking Fault Energy on Mechanism of Plastic Deformation in Nanotwinned FCC Metals
Valery Borovikov, Mikhail I. Mendelev, Alexander H. King +1
Starting from a semi-empirical potential designed for Cu, we developed a series of potentials that provide essentially constant values of all significant (calculated) materials pro…
Reflection and implantation of low energy helium with tungsten surfaces
Valery Borovikov, Arthur F. Voter, Xian-Zhu Tang
Reflection and implantation of low energy helium (He) ions by tungsten (W) substrate are studied using molecular dynamics (MD) simulations. Motivated by the ITER divertor design, o…
