| Abstract Scope |
Consumable Tool-Additive Friction Stir Deposition (CT-AFSD), also known as friction surfacing, employs a consumable rotating tool to deposit material by generating heat through friction and plastic deformation. CT-AFSD has potential applications in surface coatings and repair layers. The present study focuses on the development of a finite-volume-based heat transfer and material flow model for depositing aluminium alloy on steel substrate. This quasi-steady state moving heat source model also incorporates the temperature-dependent thermo-mechanical properties of the, tool, and substrate. The model can predict heat generation, temperature distribution, thermal cycle, torque, viscosity and material flow during the process. The thermal cycle and peak temperature are validated with the experimental study, showing a good agreement with the experiments. The influence of processing parameters on heat generation and material flow is analyzed and correlated with the resulting microstructure and mechanical properties, enhancing the understanding of the process-structure relationship in CT-AFSD of dissimilar materials. |
