Abstract

The present study aims to investigate the Aluminium oxide and Zirconium diboride particles reinforced aluminum surface composites fabricated using Friction Stir Processing (FSP). Al-6063 was used as base-metal and Aluminium oxide and Zirconium diboride were used as reinforcement media. Al 6063 is used for architectural fabrication; window and door frames, pipe and tubing, and aluminium furniture Tensile strength specimens were prepared as per ASTM –E8 Standard. Tensile strength were found using UTM. Then it is found that that the tensile strength of the composite decreases as the volume percentage of the particles added for the reinforcement increases in the composites.

Highlights

Aluminium (Al) and its alloys (Al-Si-Mg) are extensively adopted in structural, automobile, aerospace, and marine applications .Especially, Aluminum Alloy (AA) 6063 is the widely selected material for medium strength application because of its formability, and weldability.Among them, particulate reinforced AMCs (PRAMCs) have been extensively investigated in recent years due to their excellent and isotropic mechanical properties, easy fabrication and low cost
An appreciable increase in tensile strength was noted with an increase in wear properties with increase in volume of the hybrid reinforcement volume percentage.[1]A single pass Friction Stir Processing (FSP) was carried out to reinforce TiC particles in AA6083.The process paranmetrs were set at 1200 rpm rotational speed, traverse speed of 60mm/min and axial load of 10KN.The composite with various volume percentage were fabricated.The TiC particle significantly influenced the area of the composite, grain size, Ultimate Tensile strength and wear properties .[2]Friction stir processing was used as a secondary process to study the microstructural changes in the Al3 Fe Aluminium Matrix Composite cast
The sever deformation increased the dislocations and microstructural changes lead to the improved tensile properties in the cast.[3]This work focuses on the reinforcement of quartz withAA6063.The synthesised composites were of volume percentage varying from 0 to 18% with an increment of 6%.The micro hardness and wear properties improved due to the better dispersion of the quartz particles[4].This work reports the reinforcement of Fly Ash with aluminium as matrix with volume percentage varying from 0 to 16 percent

Summary

INTRODUCTION

Aluminium (Al) and its alloys (Al-Si-Mg) are extensively adopted in structural, automobile, aerospace, and marine applications .Especially, Aluminum Alloy (AA) 6063 is the widely selected material for medium strength application because of its formability, and weldability.Among them, particulate reinforced AMCs (PRAMCs) have been extensively investigated in recent years due to their excellent and isotropic mechanical properties, easy fabrication and low cost. An appreciable increase in tensile strength was noted with an increase in wear properties with increase in volume of the hybrid reinforcement volume percentage.[1]A single pass FSP was carried out to reinforce TiC particles in AA6083.The process paranmetrs were set at 1200 rpm rotational speed, traverse speed of 60mm/min and axial load of 10KN.The composite with various volume percentage were fabricated.The TiC particle significantly influenced the area of the composite, grain size, Ultimate Tensile strength and wear properties .[2]Friction stir processing was used as a secondary process to study the microstructural changes in the Al3 Fe Aluminium Matrix Composite cast. The stir zone, grain size, distribution and the mechanical properties did not change significantly but remained in short range.[6]
