Study of the Mechanical Properties of Composite Materials AA6063 Reinforced with B4C &Tio2 for Engineering Application

Abstract

Composite materials were fabricated at different volume fractions of B4C & TiO2 particles, ranging from 1%, 3%, & 5% to evaluate the impact of reinforcements on the mechanical properties of the composite materials.MMC’s can be reinforced with various oxides, carbides, nitrides and borides in particulates, whiskers or fiber form such as SiC, Al2O3 , B4C, TiC, TiB2, TiO2. B4C is an attractive reinforcement for aluminum and its alloys showing many of the mechanical and physical properties required of an effective reinforcement, in particular high stiffness and hardness. In this study the Al6063 metal composites are fabricated using stir casting route.Today trend has been changed that the advanced materials are used for vast number of structural as well as engineering applications,an investigation of Aluminium alloy (AA6063), Boron carbide (B4C) and Titanium oxide(TiO2) metal matrix composites. Aluminium is the matrix metal having properties like light weight, high strength and ease of machinability. Boron carbide which has excellent hardness and fracture toughness is added as reinforcements with TiO2 and B4C. Here, the fabrication is done by stir casting which involves mixing the required quantities of additives into stirred molten Aluminium. The present work deals with the finding of mechanical properties TiO2, B4C.Particulate reinforced Al-6063 matrix-based MMC composite. The MMCs are produced from AA6063 matrix and TiO2 and B4C. The present study is concentrated on the mechanical properties of Al-6063 metal matrix composites reinforced with micro sized titanium oxide(TiO2) and Boron carbide (B4C) particle in different weight percentage of 1,3 and 5% by using stir casting process. Hardness is tested using Micro Vicker Hardness Testing Machine .The behavior of materials is obtained by the compression test of the materials.
