INVESTIGATION OF PROCESS PARAMETERS AND PROCESSES FOR FABRICATION OF AL6061/SIC COMPOSITE BY FRICTION STIR PROCESSING FSP.

Abstract

Friction Stirr Processing FSP is an eminent technique which promises modifying mechanical . To enhance the mechanical properties of Al-6061/SiC composite by investigating the influence of processes and process parameters was the objective of this research. Design of experiment DOE was applied to investigate influential parameters of composite prepared by FSP. These parameters were tool rotational speed, tool traverse speed, number of passes and tool direction of rotation. According to Taguchi Design, experimental data was collected and then analysis of variance ANOVA, linear model analysis and signal to noise ratio S/N analysis was carried out for investigation of relative significance of each parameters. The maximum UTS obtained from the test runs and at optimum parameters were 210.73 MPa and 213.05 MPa respectively which was in good agreement with the predicted values of Minitab 19 software.
