中文摘要
高錳鋼在變形過程中產生大量的變形雙晶,因此具有很高的強度及良好的延展性。錳含量的改變會影響材料的stacking fault energy (SFE)的大小,因此影響變形雙晶的形成與發展。本實驗透過退火溫度和時間的改變,欲改變材料的微觀結構,期望達到達第三代高強度汽車鋼板(3rd AHSS)之目標性能。
本實驗發現Fe-10Mn-3Al-0.6C冷軋板材在675℃退火處理,可以得到奧斯田鐵相及少量的肥粒鐵相。退火後的試片以沃斯田鐵相為主,其中肥粒鐵相隨著退火時間的增加其體積分率及晶粒大小並無明顯的改變,且兩相成份也未隨退火時間的增加而改變。軋延的變形組織和晶界上生成的碳化物會隨著退火時間的增加而減少,使得材料的拉伸強度及延伸率隨著退火時間的增加而增加。試片經拉伸後,奧斯田鐵相中有變形雙晶的產生,因此使得材料具有高的加工硬化率、拉伸強度及延伸率。因沃斯田鐵相的成分並未隨著退火時間的增加而有所變化,故其疊差能未發生改變,因此變形雙晶效應在不同退火時間對本鋼材的影響並不大。在最佳熱處理條件下,Fe-10Mn-3Al-0.6C鋼材的拉伸強度可達900MPa,延伸率可達40%,此性質已達三代高強度汽車鋼板之目標性能。
Abstract
Twin induced plasticity (TWIP) steel is a new type of structural steel, which is characterized by both high strength and superior ductility. The key to twin formation lies in the control of the stacking fault energy (SFE) of the alloy. In this thesis, the effect of heat treatment on the tensile property and microstructure of a Fe-10Mn-3Al-0.6C alloy was studied.

After annealing at 675℃ for different times, It was found that both austenite and ferrite phases existed. The volume fraction and composition of these two phases did not change significantly by the heat treatment conditions used. When annealed at 675℃, increasing annealing time caused the carbides formed at grain boundaries gradually dissolved, and led to the higher ultimate tensile stress, 900MPa, and elongation, 40%. Deformation twins were formed in the austenite phase after tensile test in the annealed specimens, indicating that TWIP behavior occurred. The best tensile property of Fe-10Mn-3Al-0.6C alloy obtained by annealing at 675℃ is within the target property of the 3rd AHSS.
