碩士 === 國立臺灣科技大學 === 機械工程系 === 94 === The purpose of this study is to investigate the formability of hot extrusion of AZ61 magnesium alloy tube. Taguchi’s experimental approach and analysis of variance (ANOVA) technique were applied to plan experimental schedule and analyze the results. Process parameters considered in this study are the extrusion temperature, the extrusion initial speed, the extrusion final speed and the lubricants. Orthogonal array was used to design the experimental sequence. Mechanical property tests were carried out on the extruded tubes, then ANOVA technique was used to analyze the data of extruded tubes. We try to find out the connection between the process parameters and the mechanical properties of the products. Finally, optimal combination of the process parameters can be obtained for the maximum tensile strength.
