Abstract
Abstract In the present study, different weight percentages of (SiC and BN) hybrid nanoparticles that reinforced by ZA alloy have successfully been fabricated through using a stir casting technique. The Hybrid nanoparticle effects on mechanical characteristics, such as compression strength and hardness, have been investigated. The scanning electron microscopy showed the microstructure of the composite. And, the results indicated the uniform distribution of (SiC and BN) hybrid nanoparticles in the Zn-Al matrix. Also, an optical microscope was used to analyze the microstructure, this showed a dendritic structure and reinforcement particles that disappeared uniformly in the matrix with the presence of agglomerate particles. The mechanical characterization results revealed that the hardness and compression increased with increasing the hybrid nanoparticle's percentage.
