Effects of titanium diboride (TiB2) and carbon composition on deformation in aluminum 1350 TiB2 C hybrid composite numerical analysis

Abstract

This work investigates the deformation behavior of Al1350–TiB2–C hybrid composites using numerical analysis for varying TiB2 and carbon compositions (4%, 8%, and 12%). To determine the optimal composition, the composite was modeled mathematically and simulated using the finite element method. Al1350–TiB2–C is a lightweight metal matrix composite with potential for various industrial applications. The composite was fabricated by combining 99.5% pure Al1350 matrix material with varying percentages of TiB2 and carbon via stir casting. The matrix was melted and held in a furnace at 667 °C for 40 to 120 min. After melting, a vortex was formed by stirring. The goal was to mathematically model and simulate the deformation of the composites using finite elements. Deformation under different TiB2 and C compositions was simulated using the finite element method. Both theoretical and numerical stress analyses were performed. Under a maximum applied load of 80 kN, the composite with 8% (TiB2 + C) demonstrated superior performance compared to other compositions, while the 12% (TiB2 + C) composite yielded a lower damage value (0.0124). This composition (8% TiB2 + C) exhibited a stress of 261 MPa and a strain of 0.686. Consequently, the data provided by this study is relevant for automotive manufacturers.
