| Abstract Scope |
With the recent progress toward industrialization of space travel, there are more rocket manufacturers than ever, and there is a need for flexible, fast, and supply chain resilient manufacturing paths such as AM. With known tradeoffs between printability, high pressure oxygen burn resistance, and high strength for nickel based super alloys due to a propensity for strain age cracking in precipitation strengthened alloys, the 3 objectives of high strength, printability, and burn resistance result in a complex alloy design scenario. Using the ICMD® platform, QuesTek has developed alloy concepts by co-optimizing these three key properties with physics-based ICME modeling. These alloys have been prototyped and tested, including advanced characterization of nano-scale microstructure to fine tune ICME model calibration to iterate on the alloy design. |
