Financial supports of the Knowledge Foundation for the SupREme project (2018-0203) and Åforsk for the SCC-SUMAN project (18-296) are highly acknowledged. The authors would like to express their gratitude to Mr. Johannes Gårdstam from Quintus Technologies AB for performing the thermal post-treatment on the specimens. Mr. Mats Högström and Mr. Håkan Bäckström of University West deserve special recognition for their significant contributions to the room temperature LCF experiments. Chalmers Materials Analysis Laboratory (CMAL) at the Chalmers University of Technology is appreciated for the assistance with the EBSD/SEM analysis. Dr. Nitesh Raj Jaladurgam of Chalmers University of Technology and Mr. Vui Mai Nguyen of Red River College are greatly acknowledged for the analysis of the EBSD and X-ray CT results; respectively. The authors would like to thank Dr. Niklas Israelsson (Arcam-EBM); and Dr. James Shipley (Quintus Technologies AB); and Mr. Ron Morford (MetCut) for their significant contribution to the specimen manufacturing and post-processing;
