Pulse Electric Current Sintering of Copper Powders

Sintering of Zircon Powders

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...

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

Full densification of Molybdenum powders using Spark Plasma Sintering

Pure molybdenum powder was sintered using Spark Plasma Sintering under various temperatures, and holding times, under a pressure of 77 MPa and a heating rate at 700°C/min. After sintering, a carbide layer was observed at the surface. The carbide layer thickness, the relative density of the sample as well as the microhardness and the grain size of Mo were measured. The carbide thickness depends ...

Spark-plasma-sintering (SPS) of nanostructured titanium carbonitride powders

Spark-Plasma-Sintering (SPS) compaction experiments of nanostructured titanium carbonitride powders have been performed at 1600°C and 1800°C (sintering time = 1 min). The as-received nanostructured samples have been synthesized by rapid condensation from the gas-phase (high frequency plasma). The sintering results were compared with data obtained by various conventional sintering techniques suc...
