• Synthesis of Al-V alloys from high-energy ball milling and spark plasma sintering. with far-from-equilibrium microstructure: V solubility 6 orders magnitude higher than equilibrium value. Elastic modulus is much that any commercial Al alloy. Effect sintering temperature on the microstructure, hardness elastic alloys. Al- x ( = 2 at.%, 5 10 at.%) nanocrystalline structure high solid were produ...

Electrically conductive zirconia tungsten carbide composites are attractive materials for manufacturing precision components by electrical discharge machining due to their high strength, toughness and conductivity. In this study, nanocomposite ceramics with a ytterbia samaria co-stabilized 1.5Yb-1.5Sm-TZP matrix 24–32 vol.% dispersion were manufactured spark plasma sintering (SPS) at 1400 °C 15...

SiC was densified by spark plasma sintering (SPS) and the effects of surface modification powder particles on its behavior were investigated. The pressure temperature conditions set to 50 MPa 2200 °C, respectively. Specific SPS experiments at a lower (i.e. 1600 °C) performed analyze efficiency early stage densification in softer conditions. functionalization carried out grafting thin molecular ...

High-density MgB2 bulks with superior mechanical and superconducting properties were fabricated using spark plasma sintering (SPS). The sharp transition at 37.5 K proved high quality of the superconductors. Critical current density significantly exceeded that conventionally sintered bulks. Flux pinning diagrams indicated dominance grain boundary pinning, peak position 0.2. SPS showed improved 8...
