Abstract Scope |
This presentations overviews efforts to better understand of the role of Nb and Mo segregation on the early-stage oxidation behavior of IN625 prepared by by additive manufacturing (AM), with comparisons to the wrought counterpart. To accomplish this, detailed microstructural characterization was conducted to quantify the nature and extents of Nb and Mo segregation, and oxidation behavior in air was assessed in the temperature range 650-950°C for up to 20h. The measured scaling kinetics were correlated with the scale structures and the subsurface composition and phase changes in the alloy owing to thermal and selective oxidation processes. |
