| Abstract Scope |
This research developed a numerical model based on the transport phenomena that takes place during the process of fabricating Ti-Al-Cu-Si/Ti-6Al-4V composite by Direct Laser Metal Deposition (DLMD) Technique. The process was simulated using a volumetric source of heat and the investigation focused upon studying how the Ti-Al-Cu-Si/Ti-6Al-4V reinforcement layer was influenced by the absorbed volumetric energy. Processing parameters such as laser intensity and the scanning speed were varied and employed to numerically design the DLMD single and multi-tracks. The influence of the processing parameters on the characteristics of the molten pool was examined. The dimensions of the molten pool varied in accordance to an invariant energy density. Although a combination of processing parameters might have resulted at the same energy density value. The utilization of independent processing parameters produced characteristics specific to the molten pool, but energy densities are in general proportional to the resulting characteristics of the molten pool. |
