Low-temperature iron-nitride phase transformations induced by ion bombardment
We show that for the Fe–N system the combined use of ion irradiation and thermal annealing can lower the temperature for a given phase transformation. By Ar bombarding N-implanted Fe samples at 250 and 300 °C, we have induced the є-Fe2N→є-Fe2 + x N + є-Fe3.2N and the є-Fe2N→e-Fe3N +Y'-Fe4N phas...

| Sumario: | We show that for the Fe–N system the combined use of ion irradiation and thermal annealing can lower the temperature for a given phase transformation. By Ar bombarding N-implanted Fe samples at 250 and 300 °C, we have induced the є-Fe2N→є-Fe2 + x N + є-Fe3.2N and the є-Fe2N→e-Fe3N +Y'-Fe4N phase transformations, respectively. These temperatures are 50 °C lower than the ones needed to produce the same transformations by thermal annealing. |
