在此實驗中所使用的Al-2 mol% Fe2O3合金是由純鋁粉和純氧化鐵粉經過均勻混粉、冷壓和燒結所形成的合金，再經由四道次的摩擦攪拌製程在攪拌區中形成Al2O3和Al13Fe4顆粒均勻分布的微結構。經由X光繞射分析得知Al和Fe2O3反應後會先產生FeO，之後再跟Al反應還原出Fe形成Al13Fe4。改變其中一項製程參數轉速時，轉速在300 rpm時比轉速為700 rpm時，生成強化相較多，硬度值也較高。但是，改變走速時對於硬度值沒有影響。在摩擦攪拌製程之前加入球磨步驟可以讓團聚的Fe2O3更均勻分散在Al基材中，所以Al和Fe2O3之間的反應更易進行，產生較多的二次相均勻分散在攪拌區中，使得攪拌區的強度增加。本研究利用了微硬度試驗，拉伸試驗與壓縮試驗來量測Al-2 mol% Fe2O3的機械性質。
