Extrusion Die Design for Tubes with Hardness Gradient
碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 102 === This study is focused on the analysis and experiment of hot extrusion of magnesium alloy. Porthole dies with an inclination angle leads to non-uniform velocity distributions. This kind of design can make a gradient hardness tube that grain sizes at the mate...
