On the influence of solution heat treatment on the grain boundary reactivity of 316L stainless steel manufactured by laser powder bed fusion
Source abstract
Abstract
The intergranular corrosion (IGC) susceptibility of 316L stainless steel manufactured by laser powder bed fusion (LPBF) was compared with that of wrought 316L following sensitising heat treatments (aging) at 650 °C for up to 100 h. Solutionising of LPBF-316L prior to aging significantly increased its susceptibility to IGC. Microtextural characterisation revealed that prior solutionised LPBF-316L develops a high fraction of random high-angle grain boundaries, with higher geometrically necessary dislocations. These features serve as preferential sites for grain-boundary precipitation and paths for higher diffusivity during subsequent ageing, thereby promoting chromium (Cr) depletion and increased IGC susceptibility.
