Study of Mechanical Properties and Drilling Behavior of Al7075 Reinforced with B4C

Abstract

Metal grid composites (MMCs) have essentially moved forward properties including high specific strength, damping capacity, Specific modulus also great wear safety contrasted with unreinforced alloys, Aluminium 7075 need been chose as grid phase, concerning illustration constantly generally utilized by car and aviation requisition also hosting the most noteworthy quality around know business Al alloys. This contemplate investigates the mechanical also machinability properties of the aluminium 7075 fortified with boron carbide (B4C) with three aluminium reinforcements of 2%,4%,6% weight proportions from claiming B4C composites with need aid fabricated by Stir casting method. The composite tests were investigated should clarify those impact of diverse weight portions from claiming B4C support substance on the hardness, density, bending strength, ductile strength, also drilling properties of the coming about composites. Al7075 composite strengthened with 6wt. % B4C exhibited those most astounding hardness, flexural strength, density also prolongation “around those investigated examples. Aluminium grid make reinforced eventually reinforcing it for tough ceramic particles like SiC, Al2O3, and B4C and so on. This paper presents an overview of the effect of on B4C addition as reinforcement in Aluminium alloy,surface roughness test was carried on the basis of Taguchi’s L9orthogonal array taking three design factors such as material, speed and feed. Using Taguchi optimization method, optimum combination of these three factors was found 2% of B4C is good surface roughness result all among reinforcements. Surface roughness was analyzed on ANOVA (Analysis of Variance) and generates regression equation
