## Description

- description: The creep behavior of Hastelloy X fabricated by laser powder bed fusion
    was investigated, focusing on the testing temperatures of 700°C, 800°C, 900°C
    and 1000°C. For PiHA heat, the stress axis was parallel to the build direction,
    whereas for PiHC heat it was perpendicular. The creep strength of PiHA was similar
    to that of the conventional Hastelloy X at 700°C to 1000°C. The creep life of
    PiHC was one order of magnitude shorter than that of PiHA at 800°C and 900°C.
    For estimating allowable stress of additively manufactured Hastelloy X, the creep
    strength of PiHC will be minimum value. The creep ductility was much lower in
    PiHA and PiHC than in the conventional Hastelloy X at all testing temperatures.
    No large difference in creep ductility was observed between PiHA and PiHC. Double
    local minimum values of creep rate were recognized in creep rate versus time curves
    at 700°C and 800°C for PiHA and PiHC. Creep voids and cracks were observed at
    grain boundaries perpendicular to the stress axis in PiHA and PiHC. M23C6, µ phase,
    R phase and M6C particles were observed after creep exposure.
