Effect of Boron Carbide and Graphite on Machining Characteristics of Aluminium Boron Carbide Composite

Abstract:

This paper presents the mechanical and machinability properties of aluminium 6061 alloy reinforced with boron carbide composite is compared with the addition of graphite particles with AlB₄C. The composites were fabricated by stir casting process. The experimental results showed that the hardness of the composite increases with the increasing addition of boron carbide. Tests for machinability characteristics was carried out with carbide tool at different cutting speeds keeping feed and depth of cut as constant. The machining tests revealed that the addition of graphite to Al-B₄C composite has enhanced its machining properties.
