This study presents a numerical transient heat transfer analysis of Titanium Diboride (TiB₂) brake discs, focusing on their thermal behavior under extreme conditions typical of high-performance motorsports applications. Using Finite Element Analysis (FEA), the temperature distribution across the brake disc was simulated at various time steps, from initial heating to steady-state conditions. The results showed significant thermal gradients, with temperatures rising sharply as the disc absorbed heat due to high surface flux. At the 100s time step, the disc exhibited a considerable temperature increase, with the maximum temperature reaching up to 3286 K in certain regions. The integral heat absorption values indicated uneven thermal load distribution, with certain regions experiencing more heat accumulation. This analysis provided critical insights into thermal stress distribution of TiB₂, essential for understanding its wear resistance, thermal shock resistance, and suitability for brake disc applications. These findings contribute to optimizing the design of TiB₂ brake discs for enhanced performance and durability in motorsports, particularly in environments where high temperatures and mechanical stresses are prevalent.
