Carbide grain growth in cemented carbides

Acta Materialia, 2011
Abnormal grain growth is often observed in cemented carbides during sintering, but cannot be understood in terms of the classical LSW theory.

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.

Kinetics of conversion of silicon carbide to carbide derived carbon [PDF]

open access: possibleJournal 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).

Processing of silicon carbide–boron carbide–aluminium composites

Journal of the European Ceramic Society, 2009
Abstract The aim of this work was to shed light on the wetting mechanism in the SiC–B 4 C–Al system and to explore processing routes that enable infiltration of Al alloys into these ceramic powder mixtures without the formation of the deleterious reaction product Al 4 C 3 .

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.

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 ...
