Spark plasma sintering of alumina nanopowders produced by electrical explosion of wires

Alumina nanopowders produced by electrical explosion of wires were sintered using the spark plasma sintering technique. The results of XRD analysis show that the main phase in the compacted nanopowders is α-Al2O3. According to the SEM observations, the sintered alumina nanopowder consists of micron-sized faceted grains and nano-sized necked grains. The increase in sintering temperature resulted...

Niobium Wires as Space Holder and Sintering Aid for Porous NiTi

When NiTi powder compacts containing Nb wires are heated above 1 170 8C, each Nb wire reacts with adjacent NiTi powders to form a eutectic liquid which wicks into the space between the remaining NiTi powders. This creates a macropore at the location of the Nb wire while eliminating the microporosity between NiTi powders which is filled with a NiTi/Nb eutectic phase after solidification. This no...

i–6Al–4V with micro- and macropores produced by powder sintering and lectrochemical dissolution of steel wires

Ti–6Al–4V powder preforms containing parallel layers of steel wiremeshes are sintered into composites. Elongatedmacropores are created by electrochemical dissolution of the steel wires, and equiaxedmicroccepted 17 August 2009

Improvement in the transport critical current density and microstructure of isotopic Mg11B2 monofilament wires by optimizing the sintering temperature

Superconducting wires are widely used in fabricating magnetic coils in fusion reactors. In consideration of the stability of 11B against neutron irradiation and lower induced radio-activation properties, MgB2 superconductor with 11B serving as boron source is an alternative candidate to be used in fusion reactor with severe irradiation environment. In present work, a batch of monofilament isoto...
