Rene 65 is a gamma prime strengthened nickel superalloy developed by GE Aviation for manufacturing rotating disks for turbine engines. The alloy was developed to have high strength and fatigue capability for use at temperatures up to 1350F (732C), at lower cost than powder metallurgy disk alloys such as Rene 88DT or Rene 104. This alloy is now being investigated as a potential candidate for powder bed fusion additive manufacturing to provide a material with increased strength and temperature capability relative to additively manufactured alloy 718. This steady represents the first analysis of microstructural evolution for Direct Metal Laser Melting (DMLM) processed Rene 65. A comparative microstructural analysis is presented for DMLM additively manufactured Rene 65 relative to the standard cast and wrought Rene 65 material. Comparisons includes grain structure, gamma prime structure and nonmetallic inclusions between the different material forms.
