Structure-property relationships of PCGTA welds of Inconel X750 in as-welded and post-weld heat treated conditions-A comparative study

- Formation of migrated grain boundaries at the fusion zone of both ERNiCrCoMo-1 and ERNiCrMo-3 fillers.
- Improved weld strength after post-weld heat treatment.
- Higher impact toughness of the welds both in as-welded and PWHT conditions compared to parent metal.
- Structure-property relationships of the PCGTA weldments.
