This paper reports empirical relationship to predict grain size and tensile strength of friction stir welded (FSW) AA 1100 aluminium alloy joints. Six factors, five level, central composite rotatable design matrix is used to predict the experimental conditions. The empirical relationships are developed by response surface methodology (RSM) incorporating tool and process parameters.

Abstract


This paper reports empirical relationship to predict grain size and tensile strength of friction stir welded (FSW) AA 1100 aluminium alloy joints. Six factors, five level, central composite rotatable design matrix is used to predict the experimental conditions. The empirical relationships are developed by response surface methodology (RSM) incorporating tool and process parameters.
