A liquid metallurgy approach was embraced for fabricating the metal matrix composites, because of its economical nature and ease of operation. The Al7075 alloy and reinforcement Gr, ZrO 2 and B 4 C was processed into a hybrid composite using a liquid metallurgy technique. To ensure a clean and gas-free melt, hexachloroethane was used as a degassing agent during
