The Fe-Ni-Al-Cr (FBB8) ferritic alloy contains B2-ordered NiAl precipitates which, upon minor addition of Ti to the alloy, display L21-ordered Ni2TiAl sub-precipitates; this improves creep resistance, consistent with an increase in coherency strains

The ferritic Fe-Ni-Al-Cr-Mo steel (FBB8) has good creep properties up to 700 °C due to B2-NiAl nanoscale precipitates and its creep resistance can be further improved by additions of 2 or 4 wt.% Ti, as a result of sub-precipitates within the main pr

Two-dimensional dislocation dynamics (DD) simulations are performed to simulate the increase in strength of ferritic superalloys strengthened by ordered β′(B2)–NiAl precipitates. Parametric studies for three precipitate volume fractions (10, 13,

Various amounts of Ti (0, 2, 4 and 6 wt%) is added to a ferritic alloy with a nominal composition of Fe–10Cr–10Ni–6.5Al–3.4Mo–0.25Zr–0.005B (wt%) (FBB8). The microstructure and composition of the matrix and precipitate phases are characte

The FBB8-ferritic superalloy (Fe- 10Ni- 6.5Al- 10Cr- 3.4Mo- 0.25Zr- 0.005B, wt.%) modified with 2 wt.% Ti additions, was aged between 700 and 860 °C, leading to coarsening of its coherent L21-Ni2TiAl/B2–NiAl composite precipitates. The temporal ev

Ferritic alloys strengthened with NiAl precipitates are being developed for elevated-temperature applications. Due to the high concentration of Al in these alloys, they feature a relatively low density of ∼7 g cm −3 . In this paper, the high-temp
