Abstract
ABSTRACT Additive manufactured components are increasingly being applied in operational equipment. If these components are going to be used at higher temperatures, their creep behaviour needs to be verified. In the ECCC workgroup 3C an exploratory study of the short-term creep behaviour of the HASTELLOY® X alloy produced by Selective Laser Melting was carried out, with the aim of characterising the material behaviour and collecting input for the heat treatment optimisation, if necessary. Hastelloy X is a nickel-chromium-iron-molybdenum alloy for applications where a combination of oxidation resistance and high-temperature strength is required together with good fabricability. Creep test results up to about 3000 h were compared with creep results of conventionally produced Hastelloy X. Two orientations were tested: parallel and perpendicular to the building direction. In addition, the microstructure of the ruptured creep specimens was investigated to determine the fracture location/mechanism and the main microstructural features. The obtained results can be considered promising and give useful indications in the perspective of LPBF material application at high temperatures.
