Abstract: The addition of scandium in Al-Mg alloys forms a LI₂ phase, Al₃Sc, which precipitates coherently. The ability of Al₃Sc precipitates to stabilise the substructures envisages the use of strain hardening for enhancement of mechanical properties of the alloy. Al₃Zr phase possess similar crystal structure as that of Al₃Sc. Hence the present study aims to address the influence of quaternary addition of zirconium in Al-Mg-Sc alloys through Artificial Neural Network (ANN) models. The effect of composition and ageing parameters on the variation of tensile properties for Zr added Al-Mg-Sc alloys is successfully predicted by ANN technique.

Keywords: modelling; scandium; zirconium; ANNs; artificial neural networks; tensile properties; ageing; aluminium alloys; magnesium; strain hardening.
