Experimental Investigation on Mechanical and Wear Properties of Al7075-B4C-TiO2 Composite

Abstract:

Article Preview

Hybrid metal matrix composites are being widely investigated for use in light weight, high strength applications. In the present study, Aluminium alloy Al7075 was reinforced with B4C and TiO2 at 4% and 2% weight fractions respectively. The powders of the reinforcements were ball milled for uniform distribution in the Al matrix, and later fabricated by stir casting technique primarily due to simplicity and economy of the method. The specimen were prepared as per ASTM standards and later subjected to hardness, double shear, wear and impact tests and the results were compared with that of pure aluminium specimen fabricated by the same method. The hardness, shear strength, impact strength of the composite were found to be higher than pure aluminium by 4.97%, 32.28% ands 6.41% respectively.
