Influence of Surface Nanocrystallization on Two-Step Pack-Boronizing of AISI 5120 Steel
, 2023 AISI 5120 steel, which underwent 30 min single-surface nanocrystallization via supersonic fine particle bombarding (SFPB), was pre-boronized at 600 °C for 2 h, and then final-boronized at 800 °C or 900 °C for 2–6 h, i.e., two-step pack ...

Advanced Engineering Materials, EarlyView.A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

The symmetry of the boron buckyball and a related boron nanotube [PDF]
Chemical Physics Letters, 2010 We investigate the symmetry of the boron buckyball and a related boron nanotube. Using large-scale ab-initio calculations up to second-order Møller Plesset perturbation theory, we have determined unambiguously the equilibrium geometry/symmetry of two structurally related boron clusters: the B80 fullerene and the finite-length (5,0) boron nanotube.
