Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Synthesis of dense bulk MgB2 by an infiltration and growth process [PDF]
, 2014 We report the processing of dense, superconducting MgB2 (2.4 g cm-3) by an infiltration and growth technique. The process, which involves infiltration of liquid magnesium at 750 C into a pre-defined boron precursor pellet, is relatively simple, results ...

Reaction sintering of silicon oxynitride.
Journal of the Japan Society of Powder and Powder Metallurgy, 1989 Silicon oxynitride (Si2N2O) ceramics were fabricated from equi-molar mixtures of Si3N4 and SiO2 with 5 wt % Al2O3 as a sintering aid by heating at 1650-1950°C for 1 h in 980 KPa N2. The initial stage of densification was due to the solution and repreci-pitation of Si3N4 through a liquid phase of SiO2-Al2O3 system.
