Presentation Title Effect of Processing Parameters on Microstructure of PH 13-8 Stainless Steel Fabricated by Hybrid DED/CNC Manufacturing

On-Site Speaker (Planned) Michael Juhasz
Abstract Scope In-envelope hybrid manufacturing is an emerging technology which incorporates traditional CNC subtractive manufacturing into the additive manufacturing envelope. In this research, precipitation hardening Fe13Cr8Ni stainless steel (PH 13-8 SS) parts are fabricated by blown powder directed energy deposition (DED). The DED system itself is retrofitted to a Haas VF3 machining center that maintains full milling capability. The in-envelope hybrid approach allows for unique manufacturing processes involving the creation or repair of complex parts. Here, the microstructure and mechanical properties of parts fabricated with hybrid DED manufacturing are studied. Processing parameters such as laser power, scan velocity, and powder feed rate are varied between and within test coupons, and the effects of in situ milling operations is considered. Hybrid DED manufactured coupons are compared to traditionally manufactured PH 13-8 SS control samples.
