This research has been carried out to develop a new ferromagnetic shape memory alloy, which has both ferromagnetic property and shape memory effect itself. Firstly we have discovered Fe62-Cr13-Co10-Ni7-Si6-Mn2[wt%] alloy in trial and error. In this composition, we were able to improve the shape memory effect(SME) by heat treatment, however the ferromagnetic property deteriorated in the same time. In the similar system without cobalt, we have optimized the composition ratio. As a result, Fe68-Cr13-Ni7-Si6-Mn6[wt%] alloy showed an excellent SME(100%) and its saturation magnetization Ms was equal to 65.8 [emu/g]. In this research, we have made clear the role of each component, that is, influence of each element on the magnetic properties and the shape memory properties. The new ferromagnetic shape memory alloys have been produced by means of the melt spinning technique. The condition how to produce the ribbon, which contains higher manganese composition over 14%, has also clarified.In addition, we have investigated to add rare earth elements for the Fe-Cr-Si-Mn system. The samples without heat-treatment, had higher saturation magnetization over 80[emu/g] by adding nearly one percent of a rare earth element, however the magnetic property deteriorated after the heat-treatment in similarly. After optimisation, we have found out that Fe58.1-Mn26-Cr10-Si5-Nd0.7-B0.2[wt%] alloy had the perfect SME (100%) and the high saturation magnetization over 60[emu/g](under rapid cooling after heating at 970℃ for 30 seconds) and Fe57.9-Mn26-Cr10-Si4.9-Sm1-B0.2[wt%] alloy had the perfect SME(100%) and the high saturation magnetization over 87.9[emu/g](under rapid cooling after heating at 910℃ for 40 seconds). The materials developed in this research have wide application in the field of the magnetic sensors and actuators.

这项研究是为了开发新的铁磁形状记忆合金，既具有铁磁特性，又具有形状的记忆作用。首先，我们发现了试验和误差中的Fe62-CR13-CO10-NI7-SI6-MN2 [wt％]合金。在该组成中，我们能够通过热处理改善形状记忆效应（SME），但是同时检测到的铁磁特性。在没有钴的类似系统中，我们优化了组成比。结果，Fe68-Cr13-Ni7-SI6-MN6 [wt％]合金表现出出色的中小型企业（100％），其饱和磁化MS等于65.8 [EMU/G]。在这项研究中，我们清楚地清楚了每个组件的作用，即每个元素对磁性特性和形状存储特性的影响。新的铁磁形状记忆合金是通过熔体旋转技术产生的。还阐明了如何产生含有较高锰组成的含锰组成的条件。此外，我们还研究了为Fe-Cr-CR-SI-MN系统添加稀土元素。没有热处理的样品通过添加近1％的稀土元素，在80 [EMU/g]的饱和度磁化强度较高，但是在同样的热处理后确定的磁性。优化后，我们发现FE58.1-MN26-CR10-SI5-ND0.7-B0.2 [wt％]合金具有完美的SME（100％）和60 [EMU/G]的高饱和度磁化（在迅速冷却下，在970 sef 30秒加热后的迅速冷却后）和Fe57.9.9-mn26-mn26-crn26-crn26-smny4.9-sm.9-SM.9-SM。 SME（100％）和87.9 [EMU/G]的高饱和度磁化（在910℃加热后的快速冷却下40秒）。这项研究中开发的材料在磁传感器和执行器领域具有广泛的应用。
