Low-Temperature Nitridation of Iron Layers in NH3-H2 Mixtures

Effects of solute atoms on evolution of vacancy defects in electron-irradiated Fe–Cr-based alloys

“…However, the concentration of FIAs is determined integrally -that is, in the solid solution and precipitates -by this method. It is known that the solubility of FIAs in Fe is low; for example, it is just 0.02% for N at 473 K [16]. To reduce the amount of dissolved nitrogen about 0.1 at.% Al was introduced into technical alloys (see Table 1).…”

On the formation of ultra-fine grained Fe-base alloys via phase transformations

“…Slices (0.5 mm thick) of bulk materials were cold-rolled in two perpendicular directions to 2-4 m thick foils (≈99% reduction of the initial thickness). The foils were nitrided at a temperature within the range of 300 • C to 500 • C in a convection furnace [8] [8,9] (Fig. 1) we call this process ␣-nitriding (␣N).…”

Thermodynamics of the Fe-N and Fe-N-C Systems: The Fe-N and Fe-N-C Phase Diagrams Revisited

“…The same feature at low temperature is predicted using the thermodynamic descriptions from References 20, 22 and 24. The appearance of an a + e equilibrium at low temperatures is not necessarily a modeling artifact: experimental investigations [99][100][101] comparison to (i) the phase diagrams as calculated using the descriptions from Refs. [22] (dashed lines) and [24] (dotted lines) and (ii) various experimental data.…”
