本文用XPS、AES、光电子自旋极化和磁化率测量等方法研究了FeTi的表面和磁性及其在热处理和氢化过程中的变化。用中子衍射技术研究了FeTiDx（0<x< 1.9）的结构。我们解释了活化过程，中毒与氧和再活化，“氧密封”的烧结FeTi和氢化后的磁性的不可逆变化，通过表面偏析和分解的原始表面。
We have investigated the surface and magnetic properties of FeTi and their variation upon heat treatment and hydrogénation by means of XPS, AES, photoelectron spinpolarizationand magnetic susceptibility measurements. The structure of FeTiDx (0<x< 1.9) was investigated by means of the neutron diffraction technique. We explain the activation process, poisoning with oxygen and reactivation, the "oxygen sealing" of the hydrided FeTi and the irreversible change of the magnetic properties upon hydrogénation, by surface segregation and decomposition of the original surface.
