AM promises to be an innovative technology that can enable rapid manufacturing of complex parts at greatly reduced cycle time. With the maturation of SLM AM technologies there is increasing interest in applying this manufacturing method to the production of aircraft structural components, many of which are made of high-strength stainless steels. However, the current research consensus has indicated significant process sensitivities in the SLM processing of high strength stainless steels such as 17-4PH, which if not corrected may limit the application of this manufacturing method. QuesTek Innovations, partnering with the University of Louisville’s Rapid Prototyping Center have been designing and developing a new powder specification for high-strength martensitic precipitation-hardenable stainless steel optimized for the unique processing conditions and challenges of SLM processing. Development of models for different Processing-Microstructure-Property relationships and its application for alloy optimization will be demonstrated.
