Sintering Phenomena on Initial Stage in Pulsed Current Sintering.

Sintering and Heat Treatment of Titanium Alloys by Pulsed Electric Current Sintering

Effect of heat wave at the initial stage in spark plasma sintering

Thermal effects are important considerations at the initial stage in spark plasma sintering of non-conductive Al2O3 powders. The generalized thermo-elastic theory is introduced to describe the influence of the heat transport and thermal focusing caused by thermal wave propagation within a constrained space and transient time. Simulations show that low sintering temperature can realize high loca...

A Novel Approach to Develop Chalcogenide Glasses and Glass-Ceramics by Pulsed Current Electrical Sintering (PCES)

Carbon-Dispersed WCFeAl Hard Material Fabricated by Mechanical Milling and Subsequent Pulsed Current Sintering

A new metal mold material for pulsed current sintering (PCS) methods at high temperatures with higher electrical resistivity than cemented carbide molds, was fabricated using mechanical milling and PCS. The constituent (100 1 x)(WC­10 or 30FeAl) + xC (x = 0­8; mass%) hard material with dispersed spherical carbon particles were synthesized via mechanical milling of the source powders and PCS. Th...

Sintering of Fine Oxide Powders: II, Sintering Mechanisms

Conventional and new sintering mechanisms have been porous compacts is well-known in the ceramic literature. However, several reports have been presented recently that investigated using fine powders of CeO2 and Y2O3 of excellent sinterability. We have verified the validity of Herring’s show that particle/grain size can remain essentially constant up to a density of 92%, and such a resistance t...
