Abstract

Al-Mg-Si alloy is most preferred material by scientists and engineers for seeking wide range of industrial applications as its strength can be easily enhanced by cold working, grain size refining, precipitation hardening and dispersion hardening. Demand for the use of Al-Mg-Si alloy is growing rapidly because it has unique combination of properties, which make it as one of the most versatile engineering materials. In the present study, attempt has been made for systematic investigation on to know the implication of age hardening parameters like, Solutionizing Time, Aging Temperature and Ageing Time on tensile strength of Al-Mg-Si alloy using Taguchi’s Design of Experiments. A linear regression model is used to predict the response. The derived results indicate that, the aging temperature and time has imperative impact on the response whereas, solutionizing time does not have a significant effect. For a definite group of parameters, the Ultimate Tensile Strength enhanced from 154 to 210 MPa, leading to an improvement by nearly 40%.
