Heusler alloys such as Ni-Mn-Ga and Ni-Mn-In alloys have received much attention as ferromagnetic shape memory alloys and metamagnetic shape memory alloys. These alloys are formed the solid solution of bcc-base ordered structure at high temperature in the composition range from NiMn-B2 phase to Ni2MnX-L21 phase. This bcc-base ordered phase transform to the martensite phase with unique magnetic properties. In the case of alloys with Al, Ga, In, Sb of metalloid groups, the stability of bcc ordered structure have been studied well, but in the case of Si, Ge, Pb, Bi in the same metalloid groups, those are not clarified yet. In this study, Ni59Mn50-xXx(X : Si, Ge, Pb, Bi)was prepared and the phase stability of these alloys in the temperature range from 850. C to 1000. C was investigated. Alloys added small amount of Si and Ge showed the martensitic structure, and the solubility of Si and Ge in the NiMn-B2 structure is 4 at%and 7at%, respectively. Both Ni50Mn35Si15 and Ni50Mn35Ge15 alloys showed the single-phase structure. But the crystalline structure of these alloys is. 2 phase with Ni3Mn2Si2 structure not solid solution phase with bcc ordered structure. In the Ni-Mn-Ge system, 1, 2, T were newly founded. In the case of alloys with Pb and Bi, the solubility of these elements in NiMn-B2 phase is less than 1 at%and the structure of the martensite phase are 2M structure

Ni-Mn-GA和Ni-Mn-IN合金等远母合金作为铁磁形状的记忆合金和元磁形状的记忆合金受到了很多关注。这些合金在高温范围内从NIMN-B2相到Ni2Mnx-L21相的高温范围内的BCC碱有序结构形成了实心溶液。这个BCC基准的阶段转换为具有独特磁性特性的马氏体相。对于与Al，Ga，In，Metalloid基团的Sb的合金，对BCC有序结构的稳定性进行了很好的研究，但是对于同一金属基组的Si，GE，Pb，BI，这些稳定性尚未澄清。在这项研究中，制备了Ni59Mn50-XXX（X：SI，GE，PB，BI），并研究了这些合金在850。C至1000中的相位稳定性。合金添加了少量的Si和GE显示了马氏体结构，NIMN-B2结构中Si和GE的溶解度分别为4％和7AT％。 Ni50mn35SI15和Ni50mn35GE15合金均显示单相结构。但是这些合金的结晶结构是。 2具有NI3MN2SI2结构的相位不是BCC有序结构的实心溶液相。在Ni-Mn-GE系统中，1，2，t是新建立的。对于具有Pb和BI的合金，NIMN-B2相中这些元素的溶解度小于1％，而Martensite相的结构为2M结构
