| Abstract Scope |
Research has shown that the microstructural features of the feedstock powder can directly correlate to the properties of the final consolidated material for additive manufacturing, particularly in solid-state additive. 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. This research focuses on the thermal treatment of gas atomized aluminum alloy powders for solid-state additive manufacturing. The internal microstructure of the feedstock powder was analyzed using scanning and transmitting electron microscopy, energy dispersive x-ray spectroscopy and guided through the use of computational thermodynamic and kinetic models. |
