Kinetics of internal oxidation of FeAlCr alloys at low oxygen partial pressures

Fe – 1 at.%Al - x at.%Cr (x = 0, 2, 5) alloys were annealed at 1050 °C in Ar + 10 vol.% H2 gas mixture with dew point of -45 °C in order to study the behaviour of internal oxidation of Fe-Al and Fe-Al-Cr alloys under low oxygen partial pressure. During annealing an internal oxidation zone of Al2O3 is formed while Cr remains in solid solution in...

Direct Internal Methane Steam Reforming in Operating Solid Oxide Fuel Cells: A kinetic modelling approach

Direct Internal Reforming (DIR) on Solid Oxide Fuel Cell (SOFC) anodes is often considered for fuel cells systems utilising carbon based fuels. Methane Steam Reforming (MSR) is one of the most extensively studied types of DIR. The hydrogen formed by the MSR reaction can be electrochemically oxidised in the fuel cell to produce electricity, while...

Kinetics of Wüstite Formation and Reduction of Manganese alloyed Steel

The oxidation and reduction kinetics of a 1.7 wt.% Mn steel alloy with 0.1 wt.% C was studied in different ?CO?_2/CO mixtures and at different temperatures. The external iron oxide growth, the internal alloying element oxide formation and the reduction of iron oxides were observed with thermogravimetry (TG). The oxidation at 750 ? follows a...
