| Abstract Scope |
This work employs a Through Process Experiment (TPE) systematic approach to study the relationship between powder properties, cold spray (CS) processing parameters, and consolidated specimen behavior through a combination of characterization and computational models. This TPE approach allows for the systematic isolation of variables that can affect powder and CS properties. In this study, various heat treatments were applied to Al 6061 powder and used as CS feedstock using industry-standard processing parameters to study the effect of thermal pre-treatment of Al 6061 powder on cold spray properties. Techniques including SEM, EDS, XRD, nanoindentation and particle compression, tensile and indentation plastometry testing, corrosion testing, and fatigue testing were used to characterize the properties of both the feedstock powder and CS deposits. Computational thermodynamic modeling was used to guide microstructural interpretation. An additive yield strength model was employed to quantify the strengthening components introduced through the CS process. |
