Synthesis and characterization of iron aluminide

The crystallinity of the iron aluminide nanopowder is verified in the XRD. The pattern shows the presence of iron aluminide of different compositions (Fe 3 Al and FeAl). The formation of the intermetallic compound during the spray process leads to metallurgical bonding due to the high exothermicity of the formation reaction .

Quasi-one dimensional iron oxide nanowires with flat needle shape were synthesized on the iron powders by a rather simple catalyst-free thermal oxidation process in ambient atmosphere. The characterization by FE-SEM, XPS, XRD, Raman and HRTEM

The maximum alumina extraction reached ~ 60% when calcination at 600900 °C with the addition of NaOH and that could reach 82% at 900 °C with the addition of Na2CO3. Detailed analysis and characterization was carried out by using thermal gravimetric and differential scanning calorimetric analysis (TG-DSC) and X-ray diffraction (XRD).

DSC 404 F1 Pegasus®

Oxidative-induction time (OIT) measurements allow for characterization of the long-term stability of hydrocarbons. For determination of the oxidative stability, standardized test methods by means of DSC (Differential Scanning Calorimetry) are used. OIT tests by

High-temperature oxidation of FeCrAl alloy with

The resistance of FeCrAl alloys to high-temperature oxidation depends on the properties of the building up aluminum oxide. Good protective properties of -Al 2 O 3 (-alumina) scale stem from its low volatility [1, 2], slow growth rate , low concentration of crystalline defects , and good chemical stability in high-temperature corrosion environments .

Nanocoating for Activation of Energetic Metals

The conclusion is that nickel and iron coating of aluminum particles shortens the ignition time of these particles, probably due to the formation of liquid phases at low temperatures (as compared to aluminum oxide) in nickel and iron aluminide and via NiAl and Fe-Al exothermic reactions, or thermite reaction between Al and oxides of nickel
