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。
