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

IN SITU FABRICATION OF Al 2024-Mg2Si COMPOSITE BY SPARK PLASMA SINTERING OF REACTIVE MECHANICALLY ALLOYED POWDER

In situ Al2024- Mg2Si composite was fabricated by spark plasma sintering (SPS) of reactive powder. Reactive powder was obtained from mechanical alloying (MA) of elemental powders. Clad layers of in situ composite were fabricated on Al substrates by spark plasma sintering (SPS). Structural evolution during MA process and after SPS was investigated by X-ray diffractometery (XRD). Scanning electro...

Spark Plasma Synthesis (SPS) Device for Sintering of Nanomaterials

It is known that work pieces with nanocrystalline structure condition have much higher performance than those with an ordinary structure. There are known number of techniques for manufacturing of nanocrystalline materials in powder condition however a question of manufacturing bulk pieces in the same nanocrystalline state mentioned is that compaction and synthesizing of nanocrystalline powders ...

Optically transparent ceramics by spark plasma sintering of oxide nanoparticles

Fabrication of Nanostructured Cu matrix Nanocomposites by High Energy Mechanical Milling and Spark Plasma Sintering

Spark plasma sintering (SPS) is a sintering process that is capable of sintering hard worked powders in short times. This technique was used to fabricate bulk Cu and Cu-SiC nanocomposites. Pure Cu and mixed powders of Cu including 4 vol% of SiC nanoparticles were mechanically alloyed for 25 h and sintered at 750˚C under vacuum condition by SPS method. Microstructures of the materials were chara...
