Al-B4C is a Useful Nanocomposite in Aerospace, Transportation, Automotive, Military, Wear, Structural ect..
Mechanical Alloying is the Best Process for Producing Al-B4C Nano-composites.
Good Distribution of Reinforcement Particle is the Most Advantage of MA Process
Increasing Milling Time would Decrease Grain Size of Composite and Reaching Nano-Composite with Very Better Performance
Al-B4C Nano-Composite is Harder and have More Strength than Al-SiC, Al-SiO2.
