材料加工後產生的織構會使材料的機械性質具異向性，因此織構的掌控是加工時的課題。F.C.C.金屬的軋延織構依高、低疊差能分為Copper-type及Brass-type織構，兩織構間的織構過渡可由滑移變形延伸至雙晶化變形解釋，模擬方面則延伸至由Taylor機械雙晶模型完成。然而，S.R Kalidindi於1998年提出Taylor機械雙晶模型中雙晶區域的變形機制與低疊差能F.C.C.金屬的實驗現象不符。
為了改善Taylor機械雙晶模型中雙晶區域的變形機制問題並模擬低疊差能F.C.C.金屬的軋延織構，本研究藉由觀察低疊差能F.C.C.金屬軋延實驗的雙晶區域，將雙晶-基材薄層結構的變形機制加入Taylor 機械雙晶模型並將模型延伸至Relaxed constraints Taylor 模型，即本研究主要透過加入雙晶-基材薄層結構修改Taylor機械雙晶模型，再利用修改模型模擬低疊差能F.C.C.金屬的軋延織構並與實驗結果進行比較，討論修改模型於織構模擬的可行性。
若以符合Brass-type軋延織構為判斷標準，未考慮雙晶-基材薄層模型在任何邊界條件和啟動雙晶系統數的條件下皆無法模擬低疊差能F.C.C.金屬中軋延量的軋延織構，在C邊界條件且啟動一組雙晶系統、S邊界條件且啟動一組雙晶系統以及B邊界條件且啟動兩組雙晶系統的條件下則可模擬低疊差能F.C.C.金屬高軋延量的軋延織構。
考慮雙晶-基材薄層模型則是在C邊界條件下可模擬Copper方位經雙晶化產生的TC方位及雙晶-基材薄層結構異常滑移後產生的Y、Z方位。

In this study, the texture development of rolled low stacking fault energy F.C.C. metals was simulated using modified models. Here the deformation mode of the twinned region was carried out using Taylor model with mechanical twinning together with abnormal slip in the twin-matrix lamellae observed from the experiment. The simulated results of modified models were compared to the experimental results of Cu-30%Zn in order to explore the feasibility of the modified models.
It was found that the brass-type texture cannot be predicted by using modified models without twin-matrix lamellae can’t simulate the texture at medium reduction ratio. However, at high reduction ratio, this model can be applied to predict the deformation texture under C boundary condition with one twin system, S boundary condition with one twin system, and B boundary condition with two twin systems.
The modified models with twin-matrix lamellae can simulate the texture at medium or high reduction ratio under C boundary condition: TC orientation due to twinning in Copper and Y, Z orientations because of abnormal slip in the twin-matrix lamellae.
