“…In fact, with almost 2% Ti present, it is surprising that TiN was not detected by EPMA. Internal nitridation of Ti in austenitic steels has been studied [31,32]. Chen and Douglass [32] reported no TiN or AlN below 850°C because of slow nucleation, which may explain the lack of nitrides observed at lower temperatures in the present study.…”

Exposure of undoped Fe(Al) and Fe(Al)+Cr ferritic alloys in laboratory air at 900-1,000°C resulted in significant internal attack after 5,000 h, including oxides and underlying nitrides. In the most severely attacked alloys, kinetics based on mass gain and maximum penetration depth were linear; also, the deepest penetrations were a significant fraction of the specimen thickness, and were thicknessdependent. Little internal attack was observed at 700-800°C where these compositions may be used as coatings. The extent of internal attack did not decrease with increasing Al or Cr content which may indicate that rather than classical internal oxidation this attack is related to the permeation of N through a defective external scale. No internal attack was observed in alloys doped with Y, Zr, Hf or Ti where the substrate-alumina scale interface was flatter.

“…is equal to 2 -5 nm; at a size of over 10 nm the particles become rounded and their coherence is disturbed [4,5]. The maximum size of coherent particles of titanium nit-ride in austenitic alloys based on Ni and F e -N i also amounts to about I0 nm after nitriding at 1048~ [ 6 ] .…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] In the case of iron based alloys that are the focus of this paper, these alloys have been shown to have remarkable resistance to high temperature creep 14 and tolerance to high dose radiation damage. 15 Because of these properties, ODS alloys are potential candidates for the internal components of advanced power systems, including future fusion and fission reactors.…”

Nanostructured ferritic alloy is a subcategory of oxide dispersion strengthened steels intended for advanced reactor applications. The complex ultrafine grained microstructure of an advanced nanostructured ferritic alloy, as determined by electron microscopy and atom probe tomography, is summarised. Three distinct populations of precipitates were observed: 20-50 nm Ti(N,O,C), 5-10 nm diameter Y 2 Ti 2 O 7 /Y 2 TiO 5 and 1-4 nm diameter Ti,Y,O enriched nanoclusters. The first two populations were predominantly located along grain boundaries together with Cr, W and C segregation. A dense population of nanoclusters was observed both in the grain interior as well as on the grain boundaries. These nanoclusters are highly tolerant to high dose irradiation at elevated temperatures.
