Pressureless sintering of single-phase tantalum carbide and niobium carbide

Journal of the European Ceramic Society, 2013
Abstract This work presents the results of studies on the preparation of single-phase polycrystalline tantalum carbide and niobium carbide. It has been found that it is possible to obtain polycrystals with high density in the pressureless sintering process at temperatures up to 2000 °C and therefore relatively low temperatures such as for the ...

Precipitation of niobium carbides in Fe–C–Nb steel

Surface and Interface Analysis, 2004
International audienceThe precipitation of carbides in Fe-C-Nb alloy has been investigated using field ion microscopy and atom probe tomography. Analyses show that niobium carbide precipitates already exist in the state quenched from 1240degreesC ...

A study on the high temperature reaction of niobium pentoxide with niobium carbide and titanium carbide

Materials Research Bulletin, 1979
Abstract The high temperature reaction of niobium pentoxide with niobium carbide and titanium carbide has been studied to investigate the feasibility of direct preparation of NbTi alloys and the titanium deoxidation tendency of niobium. Starting with oxide-carbide charges with o:c mole ratio varying from 1.01 to 1.10 and titanium content varying from

Fabrication of niobium carbide coating on niobium by interstitial carburization

International Journal of Refractory Metals and Hard Materials, 2020
Abstract Ceramic coatings on niobium substrates are fabricated by hot-pressing the niobium with cast iron at 1100 °C. The interstitial carbon atoms diffuse into the niobium, and NbC and Nb2C precipitate in the surface, forming a ceramic coating. The total volume fraction of the ceramic phases in the coating reaches 92%, and the grain size is in the ...
