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...

Metal/Ceramic Composites via Infiltration of an Interconnected Wood-Derived Ceramic

Description:

The use of composites is increasing as they afford scientists and engineers the ability to combine the advantageous properties of each constituent phase, e.g. metal ductility and ceramic stiffness. With respect to materials design, biomimetics is garnering increasing attention due to the complex, yet efficient, natural microstructures. One such biomimetic,...
