Abstract

This paper presents the optimisation of the hardness of the material, AZ31B, reinforced with a percentage of lead and carbon nanotubes (CNTs). Currently, the new automotive era is focusing on lighter and stronger materials. Therefore, in this study, although magnesium alloy showed characteristics of high strength, yet it still needed to be enhanced in terms of strength and elongation. Hence, AZ31B was selected to enhance the strength through the addition of lead and CNT reinforcement particles. The Response Surface Method (RSM) was used to optimise the percentage composition of lead and CNT. From the RSM, a mathematical model can be obtained for the optimization of the given parameter. The RSM method was validated through an experimental analysis using the Disintegrated Melt Deposition (DMD) technique for the sample preparation. From the results, it was shown that the optimised composition due to the addition of lead was between 1% and 5%, while with CNT it was between 0.1% and 0.5%. The suggested reinforcement materials increased the material hardness of the AZ31B material by up to 27%. Hence, the proposed RSM was suitable for the optimization of the reinforcement materials.
