Advancement of Tooling for Spark Plasma Sintering
Journal of the American Ceramic Society, 2015A combined experimental and numerical study is conducted to investigate temperature nonhomogeneities within a Spark Plasma Sintering tooling setup. Radial thermal gradients through a powder compact are encountered, a cause of microstructural nonuniformities in sintered specimens, which tend to become more significant when increasing the setup's ...

Spark plasma sintering as advanced PM sintering method
Powder Metallurgy, 2002AbstractA short overview of works on spark plasma sintering (SPS) is given in the present paper. SPS is a newly developed rapid sintering technique with a great potential for achieving fast densification results with minimal grain growth in a short sintering time.

Numerical Simulation of Spark Plasma Sintering
Advances in Science and Technology, 2010A macro-scale model of spark plasma sintering (SPS) that couples electrical, thermal, stress-strain and densification components is presented. The continuum theory of sintering is incorporated enabling the evolution of the densification based on local conditions, thus a true spatial density distribution could be obtained. Specimen behavior is described

Spark plasma sintering of silver nanopowder
SPIE Proceedings, 2007The spark plasma sintering behaviour of silver nanopowder prepared by the electro-explosion method was investigated. Consolidation was carried out from 50°C to 800°C for 5 mins at 34 MPa with differential scanning calorimetry indicating a sintering onset temperature as low as 160°C and an activation energy of 86±1 kJ/mol.

Spark plasma sintering of TiNi nanopowders
SPIE Proceedings, 2004Nano-size TiNi powder prepared by electro explosion of TiNi wire process as processed by spark plasma sintering for 5 minutes at variable temperatures between 700 and 1000°C. The shape memory effect and crystallagraphy of both the powder and the sintered TiNi specimens were extensively characterized.
