Formation of the Ni3Nb δ-phase in stress-relieved Inconel 625 produced via laser powder-bed fusion additive manufacturing
{{output}}
The microstructural evolution of laser powder-bed additively manufactured Inconel 625 during a post-build stress-relief anneal of 1 h at 1143 K (870 °C) is investigated. It is found that this industry-recommended heat treatment promotes the formation of a sig... ...
