本研究以6061鋁合金添加不同重量百分比 (0.1、0.2與0.5wt.%)之奈米管與 (0.1和0.2wt.%) 之類富勒烯奈米顆粒以攪拌鑄造方式進行鋁基複合材料的製備，並探討不同重量百分比的強化相添加對機械性質與微觀組織之影響。
從實驗結果顯示6061鋁合金添加WS2奈米管在降伏強度、極限強度與延展性在添加至0.2wt.%時具有最佳值，分別提升了15.0%、20.6%以及67.8%。硬度數值方面則在添加至0.5wt.%時具有最佳值，與基材相比提高了5.1% ; 添加WS2類富勒烯顆粒在0.2wt.%時，其降伏強度、極限強度與延展性相較於基材也分別提升了12.3%、15.8%與39.3%。由微觀組織的觀察中可發現，隨著WS2奈米管或類富勒烯顆粒添加量提升晶粒尺寸皆有細化效果，添加至0.5wt.%的WS2奈米管複合材料晶粒尺寸下降至54.4μm，相比於基材平均晶粒尺寸降低了48.4%，且當WS2奈米管添加至0.5wt.%時，經SEM觀察發現奈米管有團聚情形發生，為造成添加至0.5wt.%時複合材料拉伸性質下降的因素。由複合材料強化機制之貢獻值計算比較結果顯示，兩材料熱膨脹係數差異為造成鋁基複合材料機械性質提升的主要因素。

The main aims of this research is to produce aluminum metal matrix composite. The materials used during experiment was 6061 aluminum alloy with different weight percentage of the WS2 nanotube (0.1, 0.2, 0.5wt.%) and WS2 fullerene-like nanoparticle (0.1, 0.2wt.%) to synthesize the aluminum metal matrix composite. Both aluminum and aluminum metal matrix composite were produced by stirring-casting method. Investigation of mechanical properties and microstructure of aluminum metal matrix reinforced with WS2 nanotube and WS2 fullerene-like nanoparticle have been done.
From experimental results, aluminum metal matrix composite with 0.2wt.% WS2 nanotube showed the best mechanical properties. Yielding strength, ultimate tensile strength, and ductility were improved by 15.0%, 20.6% and 67.8%, respectively. Adding 0.5wt.% WS2 nanotube showed the best result in hardness test, improved by 5.1%. With 0.2wt.% WS2 fullerene-like nanoparticle, yielding strength, ultimate tensile strength and ductility were enhanced by 12.3%, 15.8% and 39.3%, respectively. From metallography microstructure, it was found that increasing WS2 nanotube or fullerene-like nanoparticle weight percentage in aluminum metal matrix composite, results in grain refinement. By adding 0.5wt.% WS2 nanotube, the grain size of aluminum metal matrix composites was refined to 54.4μm which was reduced by 48.4% compare to the grain size of 6061 aluminum alloy ingot. SEM analysis showed that 0.5wt.% of WS2 nanotube resulted in aggregation of which decreases the tensile strength. The composite materials reinforcement mechanism contribution shows that the differences of thermal expansion coefficients between WS2 nanotube or WS2 fullerene-like nanoparticle and 6061 alloy dominate the mechanical property improvement.
