Abstract: Powder metallurgy is one of the best methods to achieve uniform distribution of reinforcement in to the matrix. In this Paper, characterization of microstructure and hardness of aluminum alloy matrix composites reinforced with boron fiber particles prepared by powder metallurgy technique are investigated. The effects of boron fiber (Coarse particles size of 120 µm and Fine particles size of 50 µm) on mechanical properties were studied. Increasing the reinforcement of boron fiber content with 5%, 10% and15% into the matrix improved the mechanical properties. The percentage of boron fiber reinforcement increasing the strength of the hardness number is also increasing simultaneously, the aluminum alloys and boron fiber particles on the microstructure and mechanical properties of the composites were investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) with Energy dispersive spectrum (EDS) analyses indicated. Analysis and observing microstructure of the composite is boron fiber particles are uniformly dispersed in the aluminum alloy matrix composites.
