Hanumantha Journal on Future Engineering and Technology 2230 – 7184 3 2 63 69 Heat treatment, Taguchi, ANOVA, Grey relation In this paper, the use of grey-based Taguchi methods for the optimization of the heat treatment process of ZE41A magnesium alloy. The purpose of optimization is to achieve high performance in material characteristics. A grey relation grade obtained from grey relation analysis is used as the performance characteristic in the Taguchi method. The material characteristics can be improved by selecting the feasible parameters. Taguchi technique has been used to optimize the parameters namely solutionizing temperature, solutionizing time, ageing temperature and ageing time. Experimental results have shown that optimal heat treatment process parameters in mechanical characterization can be determined effectively so as to improve qualities through this new technique.
