| Abstract Scope |
Commercially available powders designed specifically for additive manufacturing (AM) are becoming more ubiquitous. In an effort to determine if these designer alloys are also advantageous to use for non-traditional AM processes, such as the solid-state cold spray process, research was conducted using various AM designed alloys as feedstock. As powder properties are a function of their internal microstructure, it is therefore important to understand the microstructure in order to optimize the properties of the final parts. Powder properties can be controlled through the use of thermal treatment and analyzed through microstructural evolution. Heat treated AM powder was also tested as feedstock for the cold spray process. The internal microstructure of the feedstock powder was analyzed using scanning and transmitting electron microscopy, energy dispersive x-ray spectroscopy, and nanoindentation and guided through the use of computational thermodynamic and kinetic models. Mechanical properties were also determined. |
