Reinforcement of tungsten carbide grains by nanoprecipitates in cemented carbides

Nanotechnology, 2016
In contrast to the conventional method that obtains a high fracture strength of tungsten carbide-cobalt (WC-Co) cemented carbides by reducing WC grain size to near-nano or nanoscale, a new approach has been developed to achieve ultrahigh fracture strength by strengthening the WC grains through precipitate reinforcement.

Darmstadtium carbonyl and carbide resemble platinum carbonyl and carbide

Chem. Commun., 2004
DsC and DsCO are calculated to be very similar to PtC and PtCO, suggesting that even the latest 6d elements resemble the corresponding 5d elements chemically.

Kinetics of conversion of silicon carbide to carbide derived carbon

Journal of Physics: Condensed Matter, 2006
Carbide derived carbon (CDC) was produced on SiC by reaction with flowing Ar-3.5% Cl(2) gas at 900 and 1000 °C. The thickness of the CDC layer increased with time during high temperature exposure according to a parabolic rate equation represented by K(p) = [2.48 × 10(-6)e(-(165 000/RT))] m(2) s(-1).

Quantitative microanalysis of carbide/carbide interfaces in WC–Co-base cemented carbides

Materials Science and Technology, 1986
AbstractCarbide/carbide boundaries in WC–Co-base cemented carbides containing 6–20 wt-%Co were studied with two high resolution microanalytical techniques: atom probe field ion microscopy and analytical transmission electron microscopy. All boundaries studied, i.e.

Gas evolution from zirconium carbide, niobium carbide, and tantalum carbide powders

Soviet Powder Metallurgy and Metal Ceramics, 1986
This work was undertaken with the aim of determining the gas contents of zirconium carbide, niobium carbide, and tantalum carbide powders as functions of their processing history. A high-vacuum, high-temperature apparatus was used, connected to an oilless evacuation system and instruments for the mass-spectrometric measurement of amounts and ...

Carbides

1999
Abstract This chapter discusses the formation of free carbides and their effect on case-carburized components. It explains how alloying elements influence the composition and structure of carbide phases produced at cooling rates typical of carburizing process.
