| Abstract Scope |
At the US Naval Research Lab (NRL) we have been utilizing and developing several processing routes in order to create and tailor unique microstructures in metals and ceramics. These techniques include 2 stage sintering, aerosol deposition, high-pressure processing, microwave sintering, and electrically assisted sintering. The goal of most of these techniques is to create fully dense bulk nanostructured ceramics. The impetus for this is the many theoretical and experimental studies showing tremendous enhancements in functional properties of nanostructured materials. Nanostructure features can bring dramatic improvements to a wide range of properties including magnetic exchange coupling, thermoelectric energy conversion, and mechanical response. However, these improvements are generally only expected when porosity is negligible and the microstructural length scales are well below 50nm, which is a technological challenge, especially in nanocrystalline ceramics processing. This talk will highlight our new work and demonstrate promising processing techniques for next generation materials. |
