Understanding forgeability in highly reinforced cast-and-wrought superalloys
… precipitates upon cooling. The commercial alloy Udimet 720 is used as a benchmark to explore this mechanism. A novel testing method is devised to assess forgeability and surface cracking through laboratory-scale tests on a Gleeble thermo-mechanical simulator. The method mimics the die chilling …

Fatigue modeling of U720 – A multi-scale approach in understanding grain boundary effects on crack initiation
… fatigue response of a nickel-based superalloy, Udimet 720. This scatter can be partly attributed to the variability in the microstructure of this material. Hence, there is great interest in linking the microstructure to fatigue properties using a multi-scale approach that focuses on integrating …

Enhancing hot tooling to forge high-γ ′ superalloys
… effective hot forging of high-γ ′ alloys like Udimet 720 with increased efficiency of the forgings (in terms of the number of forged parts and minimised cracking per part). Widely applied hot tooling materials like hot work tool steels or Molybdenum alloys are severely restricted above 500 °C. …
