Fall 2011
A calorimeter for the deposition of metal during free-flight GMAW was developed for the purpose of measuring droplet heat content in Ni/WC tubular wires. By approximating the thermal gradients within the calorimeter to be second order polynomials the energy transferred to the calorimeter by the...

Investigation of Mechanical Properties, Porosity and Geometric Deviation of Lattice Structures Manufactured by Additive Manufacturing
DownloadSpring 2022
This thesis reports fabrication, mechanical characterization, finite element modeling, and geometric analysis of lattice structures. A net-shaped 316L stainless steel lattice structure composed of diamond unit cells was fabricated by selective laser melting (SLM). The cavities in the lattice...

Melt Electrospinning of Shape Memory Polymer: An Initial Examination of the Morphological, Mechanical and Shape Memory Properties of Non-woven Melt-Electrospun Polyurethane Shape Memory Polymer Mats.
DownloadFall 2020
Shape memory polymers (SMP) are a class of smart materials which are able to memorize a temporary shape and recall their original/permanent shape with the application of a stimulus. The electrospinning process has been utilized to produce fibrous SMP membranes from polymer solutions, but this...

Microstructural Characterization of Chromium Carbide Overlays and a Study of Alternative Welding Processes for Industrial Wear Applications
DownloadSpring 2014
Microstructural features of chromium carbide overlays (CCOs) were examined in this work. It was found that the microstructures can contain unmelted alloy powders. It was also shown that the structures of the primary M7C3 carbides are long hexagonal rods. Change in the microstructure from the top...

Modification of Thermal and Mechanical Properties of Polyhydroxybutyrate (PHB) through Addition of Bio-based Plasticizing Materials and Additive Manufacturing Processing
DownloadFall 2018
The non-degradable polymers currently used for commercial production and application may be inexpensive; however, their excessive use is leading to unprecedented amounts of plastic waste and extensive environmental damage. The demand for biologically-derived, biodegradable polymers is therefore...

On the Mechanical Properties and Failure of Low-Pressure Cold-Sprayed Tungsten Carbide-Nickel Metal Matrix Composite Coatings
DownloadFall 2019
Tungsten carbide-Nickel (WC-Ni) metal matrix coatings (MMC) were fabricated using a low-pressure cold spray unit. The coatings were designed according to 50, 71, and 92 weight percentages of WC in the feedstock powder. These coatings were subsequently prepared for uni-axial quasi-static tensile...
