| Abstract Scope |
Aluminum matrix composites (AMCs) have recently found utility in AM for tailoring microstructural and mechanical properties. However, optimal AMC feedstock characteristics for maximizing strength in AM components remain largely unreported. In this study, AMC feedstock powders designed for powder bed fusion (PBF) were fabricated using powder blending, mechanical alloying, and cryomilling. Powder morphology, particle size distribution, and reinforcement dispersion varied between methods and affected the resultant structure and properties in the fabricated articles. Strengthening modeling was performed on the feedstock particles before melting and after PBF fabrication to determine any effects during melting or with varying AMC production methods. |
