Effect of 6 Wt.% Particle (B4C + SiC) Reinforcement on Mechanical Properties of AA6061 Aluminum Hybrid MMC

Aluminum based hybrid metal matrix composite with more than two particle reinforcement is very much popular for heavy duty application, and the proportion of these can be controlled to achieve desired mechanical properties (strength wear resistance). AA 6061 alloys popularly used in aircraft automobile applications, tends have inferior tribological property therefore reinforcements are being made strengthen matrix. The prime objective this investigation study effect varying wt.% proportionate individual (SiC B4C) on a particular composition (6 wt.%) composite. present done evaluate dependance hard strength elongation behaviour Hardness measurement uniaxial loading techniques were characterize as-cast composites, whereas OM, XRD SEM analysis was distribution within base (AA 6061) phase. improvement properties, such as Vickers hardness, UTS, yield presented explained using various hypothesis proposed by previous studies. role clustering theory binary eutectic Mg2Si phase found key enhanced composites. Addition Alkaline Earth Metal (Mg) during synthesis process led an increase which analogous alkali metals (‘Na’ ‘Li’) addition that helps refining Eutectic
