非熱處理型鋁片一般常見的成型加工為深衝，經深衝變形後會產生凸耳現象，此與集合組織之異向性行為有相關聯性，鋁製成品於成形前須經過多道製程加工，根據前人研究，鋁板製程後段的冷軋製程及後續熱處理對集合組織的影響相當有限，因此需要在前段之熱機械製程以得到適當之集合組織，而影響其集合組織的分布即為熱機械加工製程參數，同時亦會影響晶粒尺寸之分布，其反應材料特性則為機械性質之表現，而由熱軋轉至盤捲自退火製程中將涉及微結構之變化，即再結晶之演化，因此，本研究中將聚焦於盤捲自退火製程，探討熱機製程參數對鋁合金再結晶行為之影響，並進而以再結晶為主觀察其對晶粒特性及集合組織的影響。
本研究利用EBSD分析工具量測AA1100鋁合金熱軋後經盤捲自退火於不同退火狀態下之晶粒特性與集合組織組成與分布，並建立再結晶比例演化模型、晶粒尺寸演化模型及集合組織演化模型以預測退火後微結構及集合組織之趨勢變化，最後以各模型中表示動力學之參數連結熱機製程參數對再結晶行為之影響。
實驗結果顯示當製程參數條件為低溫度、高應變速率以及高軋延量，此時完成再結晶速度達最快，而當製程參數條件為低溫度、高應變速率及低軋延量和高溫度、低應變速率及高軋延量，此時完成再結晶速度為最慢。再結晶對晶粒尺寸之影響中可觀察到當製程參數為低溫度、高應變速率以及高軋延量，此時晶粒成長速度最快；當製程參數條件為高溫度、低應變速率及高軋延量，此時晶粒成長速度愈慢。另外，由再結晶對集合組織之影響中可觀察到，針對變形集合組織，當熱機製程參數為低溫度、高應變速率及高軋延量，會促使C和B的衰減，而當製程條件為高溫度、低應變速率及高軋延量，也會促使B的衰減；針對再結晶集合組織，當熱機製程參數為低溫度、高應變速率及低軋延量，將會促使Cube與 RC20°RD的生成。

Temperature, strain rate and strain are essential parameters during hot rolling and coiling processes. These factors directly affect the microstructure and texture of aluminum sheets, and strongly determine the final microstructural characteristics of aluminum alloys. Thus, the control and optimization of these parameters are crucial for achieving the desired material properties and performance. The hot-rolled and annealed AA1100 aluminum alloys were measured by electron backscatter diffraction. The results show that the fastest recrystallization rate occurs at conditions of low temperature, high strain rate and high strain. However, the recrystallization rate decreases when the strain decreases or when decrease in the temperature and strain rate simultaneously.
