Isothermal oxidation behavior of micro-regions in multiphase Ni3Al-based superalloys
, 2020The isothermal oxidation behavior of micro-regions in multiphase Ni3Al-based superalloys (high Fe and Cr contents) was investigated at 600 °C in air. The oxide scale is mainly composed of the outer mixed oxide layer (NiO, NiFe2O4 and Al2O3) and the inner

The non-isothermal oxidation of neopentane
Combustion and Flame, 1969Abstract The cool flames and two-stage ignition of neopentane-oxygen mixtures have been studied, kinetically and analytically, to determine whether chain propagation in this oxidation regime occurs by isomerization and decomposition of alkylperoxy radicals and whether each lobe in the low-temperature ignition profile corresponds to a given mode of ...

Isothermal thermal diffusivity of iron oxide
International Journal of Thermophysics, 1980Using the flash technique, the thermal diffusivity of iron oxide has been measured as a function of time at temperatures ranging from 623 to 753 K to study the isothermal decomposition of wustite to magnetite and iron. The results are briefly discussed in terms of transformation kinetics and it is shown that the data are consistent with the growth of a

Studies on the oxidation of uranium-plutonium oxides by non-isothermal kinetics
Thermochimica Acta, 1983Abstract Kinetic data on the oxidation and oxygen chemical diffusion of uranium-plutonium oxides is important in assessing the chemical behaviour of the oxide. The oxidation of uranium-plutonium oxides, both hypostoichiometric [(U,Pu)O 2− x ] and hyperstoichiometric [(U,Pu)O 2+ x ], with varying plutonium content, was studied by non-isothermal ...

Isothermal oxidation behavior of NiAl and NiAl-(Cr,Mo) eutectic alloys
Corrosion Science, 2019Isothermal oxidation behavior of NiAl, NiAl-34Cr, NiAl-28Cr-6Mo and NiAl-10Mo for up to 1000 h at 900 °C was studied. Post-mortem inspection was performed and the oxidation mechanism was analyzed.
