Spark plasma sintering of gas atomized Al87Ni8La5amorphous powder

Spark Plasma Sintering of a Gas Atomized Al7075 Alloy: Microstructure and Properties

The powder of an Al7075 alloy was prepared by gas atomization. A combination of cellular, columnar, and equiaxed dendritic-like morphology was observed in individual powder particles with continuous layers of intermetallic phases along boundaries. The cells are separated predominantly by high-angle boundaries, the areas with dendritic-like morphology usually have a similar crystallographic orie...

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 Sintering of Negative Temperature Coefficient Thermistor Ceramics

Application of Spark Plasma Sintering for Manufacturing of Thermoelectric Materials

V-VI thermoelectric compounds like Bi2Te3-based alloys are well known for room temperature applications like Peltier coolers or thermogenerators. Their anisotropic physical properties and mechanical weakness are a problem for the manufacturing. To overcome the mechanical problem Spark Plasma Sintering (SPS) was used. 2 inch Wafers of polycrystalline bismuth telluride based n-type and p-type the...
