Investigation of mathematical model to optimise the mechanical properties of friction stir processed AA6082

摘要

Friction stir process (FSP) is a creating solid state joining process in which has been widely used in modern areas of industrial applications. The friction stir processing parameters are tool rotational speed, welding speed and axial load plays a significant role in deciding the processing qualities. In this examination central composite design (CCD) procedure and scientific model was developed by response surface technique with three parameters, three levels and 20 runs, was utilised to create the relationship between the FSP parameters (rotational speed, welding speed, axial load,) and the reactions [tensile strength, yield strength (YS)] were analysed. Proficiency of the established models is affirmed using analysis of variance (ANOVA). The 'MINITAB' computer programs were used for polynomial regression and graphical investigations of data were assembled.
