Abstract

In the current study, an investigation made on fabrication of 37 micron B4C particles reinforced Al7475 alloy composites and evaluation of mechanical properties. Al7475-2, 4 and 6 wt. % of B4C composites were synthesized by liquid stir casting process. Microstructural characterization was carried out by using scanning electron microscope and energy dispersive spectroscope. Prepared composites were evaluated for mechanical properties as per ASTM standards. Scanning electron micro photographs revealed the distribution of B4C particulates in the Al matrix and were confirmed by EDS analysis. Further, B4C particulates reinforced composites were shown more enhanced hardness, ultimate tensile strength and yield strength as compared to Al7475 alloy. Ductility of Al7475 alloy was decreased with addition hard ceramic particles.
