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...

Low temperature spark plasma sintering of YIG powders Authors: L. Fernandez-Garcia

A transition from a low to a high spin state in the magnetization saturation between 1000 and 1100 oC calcination temperature is observed in YIG powders prepared by oxides mixture. Spark plasma sintering of these powders between 900 and 950 oC leads to dense samples with minimal formation of YFeO3, opening the way to cosintering of YIG with metals or metallic alloys. The optical properties depe...

Spark Plasma Co-Sintering of Mechanically Milled Tool Steel and High Speed Steel Powders

Hot work tool steel (AISI H13) and high speed steel (AISI M3:2) powders were successfully co-sintered to produce hybrid tool steels that have properties and microstructures that can be modulated for specific applications. To promote co-sintering, which is made difficult by the various densification kinetics of the two steels, the particle sizes and structures were refined by mechanical milling ...

Spark Plasma Sintering of Commercial Zirconium Carbide Powders: Densification Behavior and Mechanical Properties

Commercial zirconium carbide (ZrC) powder is consolidated by Spark Plasma Sintering (SPS). Processing temperatures range from 1650 to 2100 °C. Specimens with various density levels are obtained when performing single-die SPS at different temperatures. Besides the single-die tooling setup, a double-die tooling setup is employed to largely increase the actual applied pressure to achieve higher de...
