Oxide dispersion strengthened nickel based alloys via spark plasma sintering

Chemical Synthesis and Oxide Dispersion Properties of Strengthened Tungsten via Spark Plasma Sintering

Highly uniform oxide dispersion-strengthened materials W-1 wt % Nd₂O₃ and W-1 wt % CeO₂ were successfully fabricated via a novel wet chemical method followed by hydrogen reduction. The powders were consolidated by spark plasma sintering at 1700 °C to suppress grain growth. The samples were characterized by performing field emission scanning electron microscopy and transmission electron microsco...

Optically transparent ceramics by spark plasma sintering of oxide nanoparticles

Novel highly scalable carbon nanotube-strengthened ceramics by high shear compaction and spark plasma sintering

e report a new strategy, based on high shear compaction and spark plasma sintering, for the massive and low cost production of 100% dense eramics containing carbon nanotubes. Custom forming and stacking of flexible green sheets of record-breaking dimensions can yield an unlimited ange of three-dimensional structures. The strategy was successfully validated in the production of multi-walled carb...

Enhancement in Ti–6Al–4V sintering via nanostructured powder and spark plasma sintering

Effect of Spark Plasma Sintering on the Structure and Properties of Ti1−xZrxNiSn Half-Heusler Alloys

XNiSn (X = Ti, Zr and Hf) half-Heusler alloys have promising thermoelectric properties and are attracting enormous interest for use in waste heat recovery. In particular, multiphase behaviour has been linked to reduced lattice thermal conductivities, which enables improved energy conversion efficiencies. This manuscript describes the impact of spark plasma sintering (SPS) on the phase distribut...
