Experimental Investigation of NanoB₄C-NanoGr Reinforced AA7075 Alloy Hybrid Nanocomposites

Abstract

The purpose of this research is to experiment with different weight percentages of nanoB₄C (5%, 10%, and 15%) in order to develop nano B₄C/graphite-reinforced AA7075 alloy composites. An analysis of the morphological and mechanical behavior of the material was carried out using SEM in accordance with ASTM E8, E9, E23, and D790. All of the reinforcement particles are distributed uniformly throughout the matrix alloy, and there are no porous portions left over. Composite materials have a hardness of 30.18 percent, an ultimate tensile strength that is 40.93 percent higher, and a compressive strength that is 19.73 percent higher than the base material. The flexural strength of the material is improved by 26.75% when the matrix dislocation density and elastic modulus fluctuations are higher. There was a 66.21% increase in impact strength as a result of reduced porosity and grain refinement.
