| Outline of Final Research Achievements |
Enhancement of thermal stability of a”-Fe16N2 was studied by doping a third element which interacts strongly with nitrogen atoms. The doped a”-Fe16N2 samples were prepared in two steps; oxide-to-metal reduction in a H2 stream and subsequent metal-to-nitride conversion using an NH3 stream. We have succeeded in finding conditions to produce high purity gallium-doped a”-Fe16N2 samples (purities > 90%). Thermal stability of thus-formed samples was studied and found to be similar to that of non-doped samples (a”-Fe16N2).
