Abstract
This study investigates the transient thermal behavior of Ti6Al4V alloy using computational fluid dynamics (CFD) simulations. The primary objective is to characterize the alloy’s heat-conduction performance under controlled thermalloading conditions. A dual-scale modeling approach was employed, combining a simplified body-centered cubic (BCC) lattice structure to represent the β-phase and a macroscopic solid domain to simulate the bulk material response. The simulations were performed over a 10-minute interval, with thermal data extracted at 1-, 3-, 5-, and 10-minute time steps. The results indicate delayed, uneven heat propagation in Ti6Al4V, attributed to its intrinsically low thermal conductivity (6.5 W/m·K). The findings provide insight into the alloy’s thermal limitations, particularly in applications requiring efficient heat dissipation. The study demonstrates the potential of CFD as a predictive tool for evaluating thermal performance in advanced metallic materials.
