<p>This work reports the effect of powder heat treatment on the tensile properties and microstructure of cold-sprayed AA7075. High-quality, cold-sprayed AA7075 material can be produced with a range of powder microstructures, but the tensile properties when using powders produced by gas atomization are suboptimal. Two types of heat treatment, overaging and solution treatment, were used to modify the intermetallic content of the starting powders. Cold spray deposits using as-atomized, overaged, and solution-treated powders were produced using high-pressure cold spray with helium as the spray gas. The microstructure and nanostructure of the starting powders and the resultant deposits were characterized using a combination of SEM and STEM imaging and diffraction techniques. The powder heat treatment increased the ductility in both cases, with overaging doubling the ductility of the as-atomized material. The solution-treated powder produced a deposit with the same yield strength as the as-atomized material and with a 30% increase in ductility. Fractography demonstrated a difference in the overload fracture mechanism between the three specimen types, which STEM imaging reveals results from differences in microstructure and particle bonding at the interface between individual particles.</p>
