In the present work, hybrid composites made of Al7075 alloy with B4C and graphite were produced using a liquid metallurgical process. Al7075 alloy was utilized to create hybrid composites that had 3–6 wt% of B4C particles and a constant 2 wt% of graphite particles. Microstructural analysis using SEM and EDS was done on the produced composites. The density, hardness, ultimate, yield strength, and elongation as a percentage were calculated using ASTM standards. Graphite and boron carbide particles were equally dispersed throughout the Al7075 alloy, according to SEM photographs. EDS patterns showed that the Al7075 alloy contained hybrid particles. Adding dual particles to the matrix reduced the density of Al alloy composites. The additions of dual particles improved the hardness, ultimate and yield strengths of the Al7075 alloy. EDS patterns showed that the Al7075 alloy contained hybrid particles. Adding dual particles to the matrix reduced the density of Al alloy composites. The distinctive fracture behaviors of the Al7075 alloy and its composites were further illustrated using tensile force micrographs.

摘要

In the present work, hybrid composites made of Al7075 alloy with B4C and graphite were produced using a liquid metallurgical process. Al7075 alloy was utilized to create hybrid composites that had 3–6 wt% of B4C particles and a constant 2 wt% of graphite particles. Microstructural analysis using SEM and EDS was done on the produced composites. The density, hardness, ultimate, yield strength, and elongation as a percentage were calculated using ASTM standards. Graphite and boron carbide particles were equally dispersed throughout the Al7075 alloy, according to SEM photographs. EDS patterns showed that the Al7075 alloy contained hybrid particles. Adding dual particles to the matrix reduced the density of Al alloy composites. The additions of dual particles improved the hardness, ultimate and yield strengths of the Al7075 alloy. EDS patterns showed that the Al7075 alloy contained hybrid particles. Adding dual particles to the matrix reduced the density of Al alloy composites. The distinctive fracture behaviors of the Al7075 alloy and its composites were further illustrated using tensile force micrographs.
