Synthesis and Tensile Characterisation of B4C Particles Reinforced Al7475 (Al-Zn) Alloy Composites

Abstract

This experimental research analyses tensile and microstructural behaviour followed by Al7475 (Al-Zn) metal alloy with 3 and 6 wt% of composites of B4C. The liquid metallurgical technique was used in this analysis for creating the Al7475 alloy with 3 and 6 wt% percentages of B4C particle composites. Additional techniques such as EDS/SEM were also employed in this analysis to determine the microstructural behaviour. ASTM Standards are followed to study the mechanical behaviour of Al7475 alloy with B4C-reinforced composites. The incorporation of B4C particles into Al7475 resulted in extreme characteristics in the field of the composite material thereby enhancing its maximum application. By combining different materials, the hardness and tensile strength of the composites improved. Tensile fractured surfaces indicated the brittle and ductile mode of fracture behaviour in the Al7075-B4C composites.
