Synthesis of Bulk Micro- and Nano- Granular Materials Through Direct Current Sintering

Abstract

The University of Alabama (UA) proposes to acquire a direct current sintering system for the consolidation of powders. This unit will complete the powder manufacturing and modification equipment currently installed at UA, notably, conformal coating and ballmilling systems as well as gas atomization hardware. In particular, the acquisition of the direct current sintering unit will bridge the unique capabilities afforded by the conformal coating system to ARO program outcomes. Specifically, the direct current sintering system provides a low temperature consolidation route for ultra-high temperature ceramic-metalmatrix composites as well as bulk manufacture of nanocrystalline materials. The direct current sintering unit enables greater flexibility and control over processing parameters and resultant microstructures that will support improve fidelity in (thermo)mechanical testing. Thus, research into both extreme condition material classes (ultra-high-temperature ceramics and nanocrystalline materials) will benefit from the consolidation capability provided by the direct current sintering system.
