Influence of Ultrasonic Vibration towards the Microstructure Refinement and Particulate Distribution of AA7150-B4C Nanocomposites

Aluminum-based metal matrix composites with single or multiple ceramic reinforcements are finding application in the aerospace and automobile industries. In this research work, novel AA7150-B4C (aluminium7150 alloy–Boron carbide) nanocomposites were successfully fabricated, through liquid metallurgy route via stir casting method, incorporation of B4C nanoparticles different weight percentages using a sequence vortex technique double process ultrasonication. The formed have been thoroughly studied for microstructure refinement, nano-particulate distribution, bonding by making use optical microscopy (OM) scanning electron (SEM) studies (respectively). addition, analyzed density, porosity, elemental composition. Further, tested investigation mechanical properties, like micro-hardness tensile strength, to investigate influence ultrasonic vibration on arrangement nano-particulates. analysis indicated that properties as-cast condition significantly improved gain 57.7% strength 24.5% hardness compared native AA7150 material.
