本實驗利用摩擦攪拌的製成方式，製作奈米氧化鋯鋁基複合材料，已成功製作出不同重量百分比氧化鋯鋁基複合材料，且分析結果顯示強化顆粒皆均勻分散在鋁基材中。由X-ray 繞涉分析結果發現氧化鋯與鋁基材經五道摩擦攪拌製程；於最高溫度505ﾟC的環境下，會反應產生Al3Zr、Al2O3的反應物，且鋁基複合材料中的Al3Zr皆為tetragonal D023 結構。5083 鋁合金經摩擦攪拌後，晶粒尺寸有明顯的被細化(約2.6 μm)，且隨複材中添加氧化鋯含量的增加；鋁晶粒尺寸有越來越小的趨勢，當含氧化鋯粉量達15.3 wt% 時鋁晶粒約細化為0.66 μm。
機械性質方面，添加氧化鋯顆粒能有效的強化鋁基材，當氧化鋯含量為15.3 wt%時硬度提升為158Hv，此值幾乎為母材5083 鋁合金硬度的兩倍。而降伏強度由125 MPa(母材)增強至400 MPa(Zr 15.3 wt% )，雖然氧化鋯的添入能有效的強化基材，但相對的會降低材料的延展性。

We applied the Friction-Stir Process (FSP) to make the ZrO2 /5083 Al
alloy composite material, and analyzed its physical properties in different aspects. Different weight percents of nanometer composite materials, ZrO2/Al, with well distributed strengthening grains were manufactured with the FSP which was used for five runs on ZrO2 along with the matrix material, aluminum, at 505°C, and created reactants of Al3Zr, tetragonal D023 structure, and Al2O3, identified with X-ray diffraction analysis.
The grain size of 5083 Al-alloy could be finer, around 2.6μm, by the FSP. This study suggests that increasing the addition of ZrO2 into the Al matrix could make the grain size of aluminum finer. We found that the Al grain size would be able to down to 0.66μm, as 15.3 wt% of ZrO2 powder was reached.
The mechanical properties of the Al-matrix material could be also modified by adding ZrO2 that reduces the ductility but boosts the strength of the matrix material. When we put 15.3 wt% of ZrO2 powder, 5083 Al-alloy attained the hardness of 158Hv, almost twice of hardness of the original alloy material, and its yield strength also increased from 125MPa to 400MPa as well.
