INVESTIGATION OF THE MECHANICAL PROPERTIES OF ALUMINIUM ALLOY (LM6) REINFORCED WITH HEMATITE METAL MATRIX COMPOSITES

Abstract

Aluminium LM6 alloy reinforced through Hematite particulate matter composite were advanced by stirrer casting process with dissimilar weightiness proportions of Hematite particulate matter from 0 to 12 wt.% in stages of 3 wt.%. The stirrer casting method is used to fabricate the metal matrix composites based on aluminium alloy and then investigate the microstructure of the prepared specimen and find out the Hardness strength, Compressive strength and Tensile strength of the mechanical properties. In the present study a modest attempt has been made using a hematite reinforcing material to manufacturing an aluminium based metal matrix composite, with an objective to make aluminium metal matrix composites by using low conventional casting technique and to obtain the delivery of reinforced material uniformly. To achieve this objective, stirrer casting process has been implemented. Aluminium (LM6) alloy and reinforcing material hematite has been chosen as matrix respectively. The result exposed that increased the reinforcing material hematite both heat treated and un heat treated specimens increases the Hardness Strength, Compressive Strength, Tensile Strength of the specimen and percentage of Elongation is decreases.
