Abstract Scope |
AF9628 low alloy steel is a type of novel steel known for its low cost, high hardness, and outstanding tensile performance. However, the processing methods of AF9628 have been less studied in the additive manufacturing field. As the balance of hardness and tensile results is closely related to the cooling process during manufacturing the process window and its relationship to resultant tensile properties were explored. By using the DED method, specimens of this steel were successfully fabricated, and tensile test results were obtained. The AF9628 steel can be manufactured for tailored properties with the DED process by controlling the cooling method. This work was funded by ARL - GVSC under cooperative agreement W911NF-20-2-0251. |
