In this study, steel fiber-reinforced titanium/aluminum composite plates were prepared using the explosive welding method. The smooth particle hydrodynamics method (SPH) in AUTODYN software was used to simulate the effect of steel fibers on the movement pattern of metal jet particles and the thermodynamics of the bonding interface during the preparation of the steel fiber-reinforced titanium/aluminum composite plates. The results showed that addition of steel fibers blocked the continuous impact of the jet particles on the metal surface, resulting in accumulation of high-temperature molten particles around the steel fibers. This effect created an environment of extremely high heat, high pressure, and high strain rates. Subsequent characterization analysis through various tests showed the simulation results were consistent with the experimental results. Addition of steel fibers had insignificant effect on the bond quality of the metal composite plate. Tensile experiments showed that addition of steel fibers significantly improved the tensile properties of the titanium/aluminum composite plate. A minimum increase of 30.23% was observed for a steel fiber diameter of 0.35 mm, and a maximum increase of 50% was observed for a steel fiber diameter of 0.5 mm. [ABSTRACT FROM AUTHOR] |
