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 ...

Characterizations and boron diffusion modelling on the AISI H13 steel [PDF]
Journal of Mining and Metallurgy. Section B: MetallurgyA kinetic approach accounting for the linearity of boron profiles through the boronized layers on AISI H13 steel was developed. It aims to track the temporal evolution of the thicknesses of the FeB and (FeB + Fe2B) layers by considering new expressions ...

Wear behaviour of plasma paste boronized of AISI 8620 steel with borax and B2O3 paste mixtures [PDF]
, 2013 In the present study, AISI 8620 steel was plasma paste boronized (PPB) by using paste mixtures with different borax and B2O3 percentages. The PPB process was carried out in a DC plasma system at 973, 1023 and 1073 K for 5 h in a gas mixture with 70% H2 ...

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.
