本篇論文主要探討鐵-9wt%鋁-30wt%錳-1.6wt%碳合金在淬火狀態和經過不同溫度時效熱處理後之顯微結構的變化，以及討論顯微結構對合金機械性質的影響。
合金在淬火狀態或經過550℃到850℃不同溫度短時間的時效熱處理可觀察到細小κ´碳化物在晶粒內析出而晶界上不會有析出物，因而可使合金強度增加且對延性不會有太大影響。但合金經長時間時效後，除了晶粒內有細小κ´碳化物之外，晶界上還可以觀察到在淬火過程中所形成的細微κ´碳化物與粗大的κ´碳化物共存的現象。這種析出現象將造成合金的強度及延性均隨著時效溫度升高而降低。另外以掃描式電子顯微鏡觀察試片的拉伸破斷面後，所得到的結果與所觀察到的相變化過程相當符合。合金經過550℃時效熱處理後強度增加且為延性斷裂；而經過850℃時效熱處理後，合金強度與延性均迅速降低，破壞型態主要為沿晶斷裂，伴隨部份的穿晶破壞模式。
