Germany: Testing Creep Properties in 3D Printed Single Crystal Ni-base Superalloys (US)

German researchers explore creep properties in superalloys, detailing their findings in the recently published ‘Creep properties of single crystal Ni-base superalloys (SX): A comparison between conventionally cast and additive manufactured CMSX-4 materials.’ The authors compare both microstructures and the creep properties of two different types of single crystal Ni-base superalloys. Single crystal Ni-basesuperalloys (SXs) are extremely relevant to applications today like aerospace, energy, and more; for example, these metals can be used to create turbine blades—but they must be able to handle mechanical loads in extreme temperatures, over 1000 °C—and operate within the creep regime. CMSX-4 materials possess what the researchers refer to as good creep strength because they are composed of refractory elements (W, Ta, Re)
