The Influence of Mixing Manner on Microstructure and Mechanical Performance of B4CP/2024Al Composites

Abstract:

The microstructures and tensile performance of B4C particulate reinforced 2024 Al alloy matrix composites produced by mechanical alloying and common blending techniques were investigated. The results showed that mechanical alloying was an effective way to fabricate the particulate reinforced Al matrix composites over common blending. The samples by different mixing techniques exhibited a clean and chemical products free interface. Tensile strength and elastic modulus of the composites was higher than that of the based alloy at the expense of ductility. The composites by common blending exhibited a more ductile fracture surface in contrast to specimen by mechanical alloying.
