Mechanical Characterization of Hybrid Metal Matrix Compositions

EasyChair Preprint 8565

Abstract

Ever since the Wright brothers flew their ‘heavier-than-air’ machine, the aviation industry has grown in great leaps and bounds. Because aircrafts were getting faster and/or bigger, the need to develop newer materials took centre stage- the use of wood and fabric gave way to stronger metallic structures (built predominantly using aluminum and its alloys). However, ceramics and composite materials are slowly replacing these too. Since the need to develop more efficient aircraft hasn’t subsided, the requirement for better materials is still in great demand.

In this thesis, considers the potential of use Aluminum alloy 7075 And Boron carbide (B4C) metal matrix composite (MMC) with particular reference to the aerospace industry.Initially, the required properties are identified, after which, the work explores pure aluminum and its importance in the industry along with its limitations. Using these limitations, MMC’s were recommended as a possible replacement for aluminum and it is seen that the exact set of properties depend on certain factors. In this project, hardness and tensile strength experiments have been conducted by varying mass fraction of Boron carbide (6%, 8%, and 10%) with Aluminum7075.

The Rockwell cum brinell hardness testing method was used to determine hardness ,Bending strength and universal testing machine is used to find the tensile properties for different compositions of aluminum 7075- Boron carbide  particulate metal matrix composite.

Keyphrases: Alloys, Metal matrix composite, bending strength, boron carbide.
