近年來綠色能源科技的發展，人們在科技產品的要求上不僅要求輕薄短小，更要高效能，磁石材料在3C科技產業內具有推動進步的能力，其中又以釹鐵硼材料的高磁能積表現最為優異，在熱壓變形後的釹鐵硼磁石具有在{001}方向的磁晶異向性。
本研究是藉由進行不同的熱變形製程，使得試片變形以達到良好的磁晶異向性，分析方法以電子背向散射(Electron backscatter diffraction, EBSD)的相鑑定與X光繞射儀(X-ray Diffraction, XRD)分析釹鐵硼材料磁石之顯微組織及優選方位(Preferred orientation)。XRD分析結果顯示釹鐵硼合金為Nd2Fe14B的四面體結構，而熱壓型釹鐵硼磁石在<00L>方向上隨著壓縮量的上升有明顯的優選方位，EBSD與XRD之{001}極圖的量測與其結果相符，由此種方式可以知道EBSD與XRD同時具有量測優選方向的能力，文獻上多呈現以壓縮量的不同去量測其磁性質的差異，本研究從優選方向結合磁性質的比較，可以更容易以微觀組織的分析側向得知其磁性質的優異程度。
而在微觀的分析上，我們從光學顯微鏡與電子顯微鏡觀察出其隨著壓縮量的不同，呈現不同的樣貌，藉由計算其薄帶與晶粒的大小，加以佐證在不同的變形量及製程溫度下，其所造成的微觀組織的不同，進而探討微觀組織對磁性質的影響，而從XRD的數據中，我們藉由取出其強度與未變形的資料庫的強度做比較，可以求得一指標係數-織構係數，由此算出其結晶面是否具有優選方向的性質，此性質所具的代表性為巨觀下的分析，另外在EBSD的數據分析上，我們藉由PF的分析，可以算出不同的試片在{001}方向上的強度貢獻，藉這樣的分析，可以從微觀中加以佐證與巨觀下的性質是否相符，而也使用SQUID-VSM得到試片的磁特性，再與其微觀組織分析一起討論，將會得知變形量與磁性質及微結構三者彼此的關係。

In our research, we want to study for different deformation degrees would influence the texture coefficient and preferred orientation property. We use the CSC GLEEBLE-1500 to do the hot pressing, doing two parameters by three different working temperature and four different deformation degrees to compare with. From our results, the deformation degrees increase help to increase the anisotropy property, and also increase the magnetic energy product. The best parameter is working temperature under 750oC, and a deformation degree of 65%.
