Mechanical Properties of Al₂O₃ Reinforced Cast and Hot Extruded Al Based Metal Matrix Composites

Abstract:

The Synthesis of aluminium matrix composites is receiving considerable emphasis in meeting the requirements of various industries. Due to the desired properties such as low weight, high specific strength, good corrosion resistance and excellent wear resistance, they have received a great interest in the recent years. Metal-matrix composites (MMCs) based on aluminium and magnesium has emerged as an important class of materials and Al₂O₃ can be considered as ideal reinforcements, due to their high strength, high aspect ratio and thermo-mechanical properties. The objective of this work is to reinforce Al 1100-Mg alloy with different wt% of Al₂O₃ (0, 3, 6, 9 and 12) was added by melt stirring method and Extrusion is carried out (extrusion ratio of 12.25) for the same alloy and composites. Mechanical property like hardness and tensile properties have been investigated for cast and extruded of base alloy and composites.
