为了研究更低温度下Zr-Nb-Fe三元系中（ZrNb）2Fe相存在的成分范围，熔炼了3个合金样品，其中Fe的含量保持为33．3at．％，Nb的含量分别为5at．％，10at．％和15at．％．经700℃均匀化退火720h后，采用x射线衍射、带能谱的扫描电镜对合金进行物相及成分分析．结果表明700℃时，Nb在（ZrNb）2Fe相中的含量处于5．0at．％-13．79at．％间；文章还给出了（ZrNb）2Fe相的晶体结构数据．

To study the composition range of (ZrNb)2Fe phase at low temperatures, three samples with constant Fe content at 33.3 at. % and varied Nb content of 5 at. %, 10 at. %, 15 at. % were melted. The alloys were annealed at 700 ℃ for 720 h and then quenched into water. Phase identification and phase composition were analyzed by using X-ray diffraction, Scanning Electron Microscopy as well as Energy Disperse Spectroscopy for the alloys. (ZrNb)zFe was found to exist in the composition range from (5 - 13.79) at. % Nb with the Fe fixed at 33.3 at. % at 700℃. In addition, data of the crystal structure for (ZrNb)2Fe phase were presented in the current work.
