摘要
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33.3 at.%,Nb的含量分别为5 at.%,10 at.%和15 at.%.经700℃均匀化退火720 h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.%-13.79 at.%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.
