| Abstract Scope |
Due to the solid-state nature of cold spray additive manufacturing, the properties and microstructure of the feedstock powder directly influence the properties of the final cold spray parts. Powder microstructure and properties can be controlled through optimization of powder heat treatment to elicit powder properties that produce better cold spray parts. In this study, various heat treatments were applied to Al 6061 powder to study the effect of thermal pre-treatment of powder on cold spray properties. This work highlights the differences in powder microstructure when the powders are heat treated using precise lab scale controlled and larger batch commercial scale heat treatment, and how these processing differences will influence the powder properties. Techniques including SEM, EDS, XRD, nanoindentation and particle compression, were used to characterize the properties of the feedstock powder. Computational thermodynamic modeling was used to guide microstructural interpretation. |
