| Abstract Scope |
Cold Spray Additive Manufacturing (CSAM) combines the benefits of solid-state fabrication with the versatility of additive manufacturing. One major advantage is the ability to process high-strength aluminum alloys, such as the 6xxx and 7xxx series, which have large solidification ranges that make them prone to cracking when using melt-based additive manufacturing methods. However, like other powder-based manufacturing, the mechanical properties of the printed parts depend on the characteristics of the powder feedstock, its treatment, and the subsequent processing and post-processing conditions. This study investigates the printability and properties of CSAM Al 7075, utilizing gas atomized and mechanically derived solid-state powder produced through the DirectPowder™ process. The results of this study will provide insights between powder feedstock, heat treatment, and mechanical properties, ultimately contributing to the optimization of CSAM for high-performance applications. |
