Mechanically alloyed AlN particle-reinforced Al-6061 matrix composites: Powder processing, consolidation and mechanical strength and hardness of the as-extruded materials

This work investigates the use of mechanical alloying to produce aluminium AA6061 matrix composite powders reinforced with AlN, and the relationship among the stages of mechanical alloying, the powder characteristics, and the mechanical strength and hardness of the consolidated materials. The results showed that the brittle particles accelerate the milling process by increasing the matrix deformation and enhancing the welding and the fracture of...
