Their average sizes are 48～136nm, and particles sizes are 2.3～3.4nm,about 21～40 Nickel Iron particles on per spheroid.It is also shown that in which NiFe 2O 4 and FeNi 3 were formed by analysis of XRD and EDS.

微球的平均粒径为 4 8～ 136nm ，单个微粒的粒径 2 3～ 3 4nm ，每个复合微球中约有2 1～ 4 0个铁镍粒子，X 射线衍射和X 射线能谱分析表明，主要成分为NiFe2 O4 和FeNi3。

The results showed that the nanocrystalline bcc FeNi particles were available using carbonyl iron and nickel powders as the raw materials during the high-energy ball milling.

结果表明：以羰基铁和羰基镍为原料，通过高能球磨得到了bcc结构FeNi纳米晶合金。

After 10h ball milling, the alloy of carbonyl iron and carbonyl nickel began to form, and the sample kept its original bcc and fcc structure; after 100h ball milling, the sample became a solid solution with bcc structure; after 200h ball milling, the diffraction peak of Ni almost disappeared and the isotropic grains with D achieved, which was mainly attributed to the dislocations and disclinations of the nanocrystalline bcc FeNi suffering from severe plastic deformation by ball milling.

球磨10h时，羰基铁和羰基镍开始形成合金，但大部分Fe、Ni原子仍分别以bcc结构和fcc结构存在。球磨100h时，样品以bcc结构的FeNi合金为主，球磨200h后，样品中fcc结构Ni特征峰几乎消失，FeNi纳米晶达到最小粒径的平衡值，~8nm。高能球磨过程中，晶界区域的层错缺陷是合金化和纳米晶形成的重要因素。
