TEM observation of the reduction of wustite by Hydrogen Ion implantation

Abstract

The reduction process during hydrogen ion implantation into FeO (wustite) has been investigated by using a dual ion beam accelerator interfaced with a high voltage electron microscope (HVEM). Radiation damage and precipitates, which were generated during the hydrogen ion implantation were observed. The precipitates were generated by the reduction of wustite. The small precipitates had an orientation relationship with the wustite matrix while large precipitates became free from restrictions of the matrix.
