Experimental Analysis of the Mechanical Properties of Aluminum-Based Alloy Metal

Abstract

An Aluminum based alloy was manufactured and tested in this thesis using Pb (Lead), Mg (Magnesium), Zn (Zinc), along with Al (Aluminum) as the base alloy is three different compositions. For each of the compositions different tests were carried out individually ie. Tensile test, impact test and hardness test. From these experiments the alloy with most hardness and strength was found for specimen 03, where have maximum strength 64622.57 KN/m², Maximum hardness 67.75 HRN, Maximum impact force 117.6 𝑙𝑏𝑓 was measured which was better than the base alloys. From the experimental studies, the optimum volume fraction of alloy reinforcement in this alloy on the basis of mechanical properties and testing analysis is also determined. The hardness test is a mechanical test for material properties which are used in engineering .design, analysis of structures, and materials development. The principal purpose of the hardness test is to determine the suitability of a material for a given application, or the particular treatment to which the material has been subjected. The ease with which the Hardness test can be made has made it the most common method of inspection for metals and alloys. A method for determining behavior of material subjected to shock loading in bending, tension, or torsion. The quantity usually measured is the energy absorbed in breaking the specimen in a single blow, as in the Tension Impact Test. Impact tests also are performed by subjecting specimens to multiple blows of increasing intensity. Tensile testing, also known as tension testing, is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum elongation and reduction in area
