Description 39-50
Different types of aluminium alloy based composites are being developed nowadays by using various types of the
reinforcements to get better mechanical properties. In this research work, a new aluminium-copper alloy based composite
reinforced with 5%, 7.5% and 10% of titania (TiO2) and zirconia (ZrO2) mixer have been fabricated and also investigated
for mechanical properties like surface hardness, compressive strength, tensile strength and micro-structural characterization
has been done by using microscope, energy dispersive spectroscopy, scanning electron micro-graph with X-ray elemental
mapping and X-Ray powder diffraction. The new composite has been prepared by combining three processes like sand
mould casting, temporary wax pattern and stir casting which has never been used before for casting. Design of experiment
has been done by employing Taguchi L18 orthogonal array in this study. It has been found that all the three mechanical
properties have been escalated due to reinforcement of abrasive particles in the base alloy and the improved results of Al/Cu
composites in terms of percentage are 29.72% for hardness, 31.46% for tensile strength and 43.29% for compressive
strength successfully achieved in this work.
