Aluminum magnesium boride (BAM) and boron carbide (B4C) show great promise for engineering applications due to their high strength, hardness, impact resistance along with low mass density. Four BAM-B4C composite specimens (100% BAM, BAM + 10 wt% B4C, 20 50 B4C) produced by spark plasma sintering were characterized using electron microscopy energy dispersive spectroscopy. Mechanical properties s...
ransparent polycrystalline alumina (PCA) is a promising replacement for sapphire. Its optical properties however are highly dependent on the rain size and residual porosity which need to be controlled for real inline transmittances (RIT), that are high enough for possible applications. To achieve high RITs, doping as well as pressure assisted sintering is often used. In this study spark plasma ...
The processing conditions for preparing well dispersed silica-graphene nanoplatelets and silica-graphene oxide nanoplatelets (GONP) composites were optimized using powder and colloidal processing routes. Fully dense silica-GONP composites with up to 2.5 vol% loading were consolidated using spark plasma sintering. The GONP aligned perpendicularly to the applied pressure during sintering. The fra...
