Microstructure, Physical and Tensile Behaviour of B₄C Particles Reinforced Al7010 Alloy Composites

Abstract

In the current studies an investigations were made to know the effect of 20 to 25 micron sized B4C particles addition on the physical and mechanical behaviour of Al7010 alloy metal composites. Al7010 alloy with 4 and 8 wt.% of B4C composites were produced by stir cast process. These synthesized composites were tested for numerous mechanical properties like hardness and tensile behaviour along with density measurements. Further, microstructural characterization was carried by SEM and XRD analysis to know the micron sized particles distribution and phases. By adding 20 to 25 micron sized B4C particles hardness and tensile strength of Al7010 alloy was enriched with slight decrease in elongation. Further, density of Al7010 alloy was decreased with the accumulation of B4C particles. Various tensile fracture behaviours were observed by SEM analysis.
