High-temperature oxidation of advanced FeCrNi alloy in steam environments

High Temperature Oxidation Behaviour of Nimonic - 115 Alloy in Presence of Sodium Salts at 850OC

The high temperature oxidation behaviour of Nimonic-115 industrial alloy has been investigated in presence of  NaNO3, Na2CO3 and Na2O2 at 850oC in flowing air. The oxidation kinetics and effect of salt deposition for the period of 48 h were studied. The scale morphologies were determined on the basis of X-ray diffraction anal...

Kinetics of Ethanol Oxidation in High-Pressure Steam*

Ethanol oxidation rate in high pressure steam at the pressure of 10 MPa in the temperature ranging from 430 to 490 °C was studied with the fuel equivalence ratio of 0.4. On the assumption that the reaction order is first order, the reaction rate parameters obtained in the experiments are 10 ± 0.4 s for the pre-exponential factor and 166.5 ± 6.1 kJ·mol for the activation energy. This ethanol oxi...

High-Temperature Oxidation of Fe3Al Intermetallic Alloy Prepared by Additive Manufacturing LENS

The isothermal oxidation of Fe-28Al-5Cr (at%) intermetallic alloy microalloyed with Zr and B (<0.08 at%) in air atmosphere, in the temperature range of 1000 to 1200 °C, was studied. The investigation was carried out on the thin-walled (<1 mm) elements prepared by Laser Engineered Net Shaping (LENS) from alloy powder of a given composition. Characterization of the specimens, after the oxidation,...
