A novel microalloying strategy for superior creep performance in LPBF Inconel 718 superalloy

For high-temperature service components, excellent creep performance is critical. However, oxygen embrittlement limits the creep performance of laser powder bed fusion (LPBF) IN718 alloy. This study optimized creep performance by increasing carbon content to 0.45 wt.% and adding 0.06 wt.% yttrium (Y...
