FRICTION STIR PROCESSING (FSP) OF COPPER AND ENHANCEMENT OF ITS MECHANICAL PROPERTIES USING GRAPHITE POWDER (C)

Abstract

This project investigates change in micro structure, hardness, tensile strength and wear resistance of friction stir processed copper in multiple passes with the help graphite powder. The behavior of copper with graphite powder has been studied with single pass, double pass, triple passé and four passes. A 6 mm triangular pin and 19.95 mm diameter shoulder tool has been used for processing. The optical microscopy (OM) results are also presented for each case. The objective of this project is to investigate change in micro structure, hardness, tensile strength and wear resistance of friction stir processed copper in multiple passes with the help graphite powder. Friction stir processing has the advantage of reducing distortion and defects in the materials. The tensile test, hardness test, wear test and microstructure test has been successfully examined and results are analyzed.
