面心立方金屬變形組織、軋延織構及再結晶織構受疊差能影響甚巨，因此本研究針對面心立方金屬探討疊差能於冷軋延過程中織構演化，實驗材料為多晶鎳、銅、及黃銅，鎳、銅、及黃銅分別代表著高中低三種不同疊差能的面心立方金屬，而壓延量分別為30%、60%和90%。冷軋後以XRD和EBSD分析冷軋織構和顯微組織。
研究結果為鎳與銅經軋延90%後於β-fiber有著整體強度上升的趨勢晶體方位轉至Copper{112}<111>、S{123}<634>和Brass{110}<112>方位分量，顯示高疊差能材料其冷軋織構為Copper型織構，並於微結構出現層狀次晶粒結構以降低其系統應變能。
冷軋黃銅中則顯示於軋延30%之後為數多的晶粒因機械雙晶的產生由Copper{112}<111>轉向TC{552}<115>和接近Goss{110}<001>方位，使由Copper型織構轉變為Brass型織構；於冷軋90%時剪切帶出現並由Goss{110}<001>轉向Brass{110}<112>，顯示低疊差能材料冷軋後為Brass型織構，且剪切帶集中區域有著應變能下降之回復現象。

In this study evolution of texture and microstructure in nickel, copper and brass of fcc metals was investigated. X-ray diffraction and electron backscatter diffraction techniques were used to characterize microstructures and orientation distributions of specimens after 30, 60 and 90% thickness reductions.

It was found that nickel and copper of high and medium SFE materials show Copper-type texture, and have high orientation densities along the whole β-fiber with increasing deformation. Micro-shear bands are formed when D orientation rotates to Copper and Goss orientation.

For brass after 30% reduction the orientation of deformed grains changes from Copper {112} <111> to TC{552}<115> close to Goss {110} <001>. Furthermore, the texture type also changes from Copper to Brass type. After 90% cold rolling, shear bands occur in brass and the orientation changes from Goss{110}<001> to Brass{110}<112>.
