| Abstract Scope |
This work investigates the feasibility of hybrid dispersion strengthened aluminum MMC for electric vehicle powertrain applications such as brake rotors and gears. The hybrid composites contain fine dispersoids obtained through in-situ reactions and coarse reinforcement particles. We produced the MMC through casting and friction consolidation routes, where the casting route is mainly targeted for brake rotor applications and the friction consolidation for gears. Fine TiB2 particles were obtained through in-situ halide salt reactions as a sustainable and cheaper alternative for the casting route. Moreover, the composite becomes recyclable as a grain refiner master alloy for the casting industry. Fine Al2O3 particles are obtained through thermite-type reactions for the friction consolidation route. We measured the cast composite’s wear resistance, and the friction-processed hardness and strength to evaluate their application in electric vehicles for weight reduction and decreased non-exhaust particle emissions. |
