碩士 === 國立臺灣科技大學 === 機械工程系 === 103 === Based on the pre-assumption that reinforcement combines well with matrix, the excellent mechanical characteristics of magnesium metal matrix composites (Mg MMCs) made by adding reinforcement into magnesium provide more advanced mechanical properties than magnesium. This research aims to produce the magnesium metal matrix composite. Under the process of die-casting with stirring method, WS2 nanotubes is the main reinforcement in order to reinforce AZ31 and AZ61. In order to investigate the mechanical properties, microstructure, and the rupture of features, the casting ingots of MMCs reinforced by WS2 nanotubes, multi-walled carbon nanotubes (MWCNT) and raw material processed by T4 solid solution treatment are compared by measuring tensile properties and hardness.
