The Creep and Corrosion Performance of AM303, an Elevated Temperature Ni-superalloy Designed for Direct Metal Laser Melting: Laura Dial1; Monica Soare1; Bruce Pint2; Rishi Pallai2; Voramon Dheeradhada1; 1GE Research; 2Oak Ridge National Laboratory
The development of nickel superalloys for direct metal laser melting has proved challenging due to the inherent micro-crack susceptibility of these alloys during additive manufacturing. A new nickel superalloy, AM303, has been designed for compatibility with direct metal laser melting (DMLM) and will be presented. Most recently, long term creep performance is analyzed. Additionally, an assessment of corrosion behavior in sCO2 environment including comparisons of additively-built and polished surfaces will be presented.The information, data, or work presented herein was funded in part by the Advanced Research Projects Agency-Energy (ARPA-E), U.S. Department of Energy, under Award Number DE-AR0001120.
