Laser Powder-Bed Fusion of Elemental Powder Blends to Manufacture Precipitation and Oxide-dispersion Strengthened Aluminum Alloys

Description:

Elemental powder blends are an emerging alternative to prealloyed powders for high-throughput alloy design via additive manufacturing techniques due to their flexibility, low cost, and ease of customization. This dissertation investigates elemental alloying elements (Sc and Zr) which are high-melting and highly reactive, unlike previous work which focused on more...

Enhancing Solid Oxide Fuel Electrode Performance via Structural and Exsolution Approaches for Operation in Multiple Fuel Environments

Description:

In the face of a changing climate caused by anthropomorphic release of carbon dioxide and other greenhouse gases, major governments have committed to the reduction of CO2 and other emissions over time, requiring increased reliance on forms of carbon-free renewable energy. The inherent intermittency of renewable electricity sources creates a...
