Implications on the influence of mica on the mechanical properties of cast hybrid (Al+10%B4C+Mica) metal matrix composite

Abstract

Hybrid aluminum metal matrix composites have prominence than conventional metals. Aluminum is used as base metal in many metal matrix composites, as it is widely used in industries and researches. The low density that is obtained after alloying is the major advantages of hybrid composite. The present study involves synthesis of Al6061/B4C/Mica hybrid metal matrix composite using stir casting method by mica particles as 3, 4, 5, 6wt.%, while maintaining 10wt.% of boron carbide. The best mechanical properties are reported by inclusion of 3wt.% of mica, while further addition of mica more than 3wt.% pulls down the mechanical properties and hence not sensible. The early-stage of strain hardening, and high tensile strength-yield strength ratio is observed, which concludes the fabricated hybrid aluminum composite is well suitable for automotive-related sheet forming operations.
