Abstract

The current study involves the production of composites consisting of Al2005 alloy and B4C using a liquid metallurgical technique. The Al2005 alloy is employed to fabricate composites with 4 and 8 weight percent of B4C particles. The microstructure of the produced composites is examined utilising Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). The density, hardness, ultimate strength, yield strength, and elongation are assessed according to the ASTM E8 standard for tensile testing and the E10 standard for hardness testing. The consistent distribution of B4C particles throughout the Al2005 alloy is validated by SEM. EDS analyses indicate the existence of B4C particles within the Al2005 alloy. The incorporation of lighter B4C particles into the matrix diminishes the density of aluminium alloy composites. The incorporation of particles results in an improvement in the hardness, ultimate tensile strength, and yield strength of the Al2005 alloy by 33.73 %, 36 %, and 41.84 %, respectively. The tensile fractured micrographs offer additional proof of the distinct fracture characteristics shown by the Al2005 alloy and its composites.
