| Abstract Scope |
Additive Friction Stir Deposition, a new solid-state AM technology based on friction stir welding, stands apart from established methods with unprecedented build rates and print volumes. The process, structure, properties relationship for AFSD is not fully understood; repeatability, machine parameter effects, and defect mitigation are current areas of investigation. Herein, work is exploring the processing of aluminum alloy 5180 due to its unique properties among the 5xxx series. Three distinct cast feedstock forms were deposited by AFSD and then interrogated using both non-destructive evaluation (NDE) and destructive sectioning. NDE probed material for heterogeneities using ultrasonic and radiometric methods. Material sectioning was then performed to isolate and quantify the nature of these features as well as their contributions to mechanical properties. The impact of heat treatment on both heterogeneities and mechanical properties has also been explored. |
