Abstract Scope |
Additive manufacturing holds the promise to produce geometrically complex parts which are not achievable by conventional manufacturing techniques. As with subtractive manufacturing processes, changes to the constitutive materials can have profound effects on the process and the performance of the part. In additive manufacturing, each process along the way from powder to part must be optimized to ensure ultimate success. For example, the microstructure of feedstock powder can influence how the manufacturing process proceeds.
We present results from examining how the microstructure of a AM feedstock particle changes after heat treatment. By leveraging the non-destructive nature of laboratory x-ray nanotomography, we imaged the internal microstructure of a single(~40 µm) powder particle evolving as it was annealed from its pristine state. Correlative analysis using FIB-SEM + EDS verify the chemical nature of the developing inclusions. We will discuss the implications of this analysis towards powder performance in a cold-spray manufacturing process. |
