High-temperature oxidation of Fe3Al-based iron aluminides in oxygen

Oxidation of Micro-Sized Aluminium Particles: Hollow Alumina Spheres

“…Different explanations can exist related to these whiskers. It has been demonstrated that local growth of h-Al 2 O 3 can present whisker morphology on wrought NiAl alloys [21] and Fe25Al [22] and Fe40Al [23] strips. It has also been found in aluminized and annealed titanium [24].…”

The isothermal oxidation of Fe3Al−4%Cr−(0, 0.5, 1, 2%)Mo alloys at 1000°C

“…The Al 2 O 3 grains of about 200-500 nm in diameter had about 0.26-1.07 % dissolved iron ions, depending on location (Figs. 4(a) and (b)), although Babu et al [10] had previously suggested that the Fe dissolution in the Al 2 -4%Cr-(0, 0.5, 1, 2% [13].…”

“…Therefore, it is of interest to study the high temperature oxidation of the thermomechanically treated (Cr, Mo)-alloyed Fe 3 Al, because the oxidation property is an important factor in actual applications. Previous oxidation studies of Fe-(24, 28 %)Al-(0-10 %)Cr between 700 and 1057 o C indicated that Cr accelerated the initial growth of Al 2 O 3 , and decreased oxidation resistance to a certain extent [6][7][8][9][10]. However, the effect of Mo has not as yet been properly studied.…”

Novel Nanocrystalline Intermetallic Coatings for Metal Alloys in Coal-fired Environments

“…In general, these intermetallics have superior resistance to oxidation [2][3][4][5] and sulfidation [6][7][8][9] at high temperatures. It also exhibits other generally desired attributes such as low density, good wear resistance, and low cost [10][11][12][13].…”
