Structure and properties of -carbides in duplex lightweight steels
κ-carbide in lightweight steel is studied. Its thermal stability, crystal morphology, orientation relationship, degree of lattice misfit and mechanical properties are measured experimentally. The mechanisms for the microstructural evolution of κ-carbide are considered based on the crystal structure, lattice misfit, element diffusivity, and solute partition. The hard γ/κ grain and ductile α+κ gr...

متن کاملSimultaneous determination of titanium and molybdenum in alloy steels using derivative spectrophotometry in neutral micellar medium
A simple, selective and sensitive spectrophotometric method has been developed for the individual and simultaneous determination of Ti(IV) and Mo(VI) using salicylaldehyde p-hydroxybenzoylhydrazone (SAPHBH) in presence of Triton X100, without any prior separation. Beer’s law is obeyed between 0.15-2.0 and 0.20-2.51 μgmL concentration of Ti(IV) and Mo(VI) at 470 and 410 nm, respectively. The mol...
متن کاملCatalytic hydrodenitrogenation of indole over molybdenum nitride and carbides with different structures
The hydrodenitrogenation (HDN) of indole has been studied over Mo2N and Mo2C with different structures. The difference in activity was modest and the structure of the catalysts exerted a more signi®cant effect than the chemical composition. More evident difference was observed in selectivity, and here the composition was the most important factor. Sonochemically prepared Mo2C was an active cata...
متن کاملInteraction of molybdenum hexacarbonyl with dehydroxylated alumina thin films at high temperatures: Formation and removal of surface carbides
The reaction of Mo(CO)6 with thin films of dehydroxylated alumina grown on a Mo(1 0 0) substrate above 500 K is studied in ultrahigh vacuum using temperature-programmed desorption and Auger and X-ray photoelectron spectroscopies. This results in the formation of a molybdenum carbide that incorporates a small amount of oxygen, where MoC is formed initially, becoming closer to Mo2C as the Mo(CO)6...
