本研究以Fe70Pd25Au5高相變化溫度特性為基礎，用元素Pt去取代部分或全部元素Au，提升試片的磁晶體異向性，觀察其效應。合金成分固定Fe為70at%、Pd為25at%，Pt與Au合計含量為5at%。製作Fe70Pd25Au(5-x)Ptx (x = 0、0.5、1、5) 三元和四元合金塊材，做下列比較與探討 : 生成bct麻田散相的能力(包括溫度誘發bct相與應力誘發bct相)、改變相變化溫度，並分析各項基本性質如微結構、磁性質、磁伸縮值、雙向形狀記憶效應的變化。
用冷輥壓製備塊材試片，發現Fe70Pd25Au(5-x)Ptx (x = 0、0.5、1、5) 三元和四元合金塊材均展現極佳的延展性。
熱機處理後的塊材試片中，A4.5P0.5-TMT1和A4P1-TMT1在室溫下結構部分為熱彈性fct麻田散相，P5-TMT1在室溫下結構為fcc母相，顯示添加Pt取代Au不會引起二次相的析出和非熱彈性bct麻田散相的生成，但使合金相變化溫度下降，並使晶格常數比值(c/a) ratio上升。
Fe-Pd-Au(Pt)三元合金A5和P5經過77K與2K低溫處理，都沒有溫度誘發非熱彈性bct麻田散相的生成；而Fe-Pd-Au-Pt四元合金A4.5P0.5和A4P1經過相同低溫處理，卻有非熱彈性bct麻田散相的生成。另外發現添加Pt能有效抑制合金中應力誘發bct麻田散相生成。
磁性質部分，證實Pt能提升試片的磁晶體異向性，而飽和磁化量以P5最高；外加磁場10 kOe、θ=90度時，磁伸縮值以A4.5P0.5的-636.6 ppm最高。
形狀記憶效應方面，添加Pt會增強合金中的固溶強化，使得雙向形狀記憶效應的回復率下降。
