Determination of the exact composition of uranium-niobium alloys

open access: yes, 1968
Electron probe microanalysis was employed to determine the exact composition of niobium in a series of uranium-niobium alloys in which a part of niobium was bound by carbon in form of carbide. Best results were achieved with uranium M line.

Corrosion Resistance of Niobium and Vanadium Carbide Layers Produced by Thermoreactive Diffusion Treatments on Spheroidal Cast Iron

open access: yes, 2017
In the present study unalloyed spheroidal graphite iron was compared with a sample alloyed with copper and nickel (Cu- Ni). Samples of those materials were treated in salt bath (a composite of sodium borate, aluminum, iron-niobium and/or iron-vanadium ...

Niobium carbide, a new cermet material with excellent properties

open access: yes, 2018
Niobium carbide is a ceramic material which can be used with excellent results to replace tungsten carbide with cobalt binder. Furthermore, it might be manufactured by classic ceramic technologies and even colloidal processing.

A comparative DFT study on physical properties of metal-substituted niobium carbide

open access: yes
The structural and mechanical properties, and the stability characteristics of the metal-substituted niobium carbides (Nb3MC4) have been investigated by using density functional first-principles calculations.
