摘要：

Laser powder bed fusion (LPBF), a metal additive manufacturing technique, was conducted on feedstock-modified 316L stainless steel (316L) powder produced by ball-milling of commercial 316L and 1 wt% additive (cerium oxide-CeO2, lanthanum (III) nitrate hexahydrate-La (NO3)(3)center dot 6H(2)O, and chromium nitride-CrN). The feedstock-modified LPBF-316L specimens were sensitized at 675 degrees C for 24 h, and the influence of additives on intergranular corrosion (IGC) was investigated following ASTM G108-94 and A262-14 standards. The LPBF-316L with La(NO3)(3)center dot 6H(2)O showed higher IGC resistance. The microstructure of the LPBF specimen was investigated and correlated to understand the improved IGC resistance of LPBF-316L with La(NO3)(3)center dot 6H(2)O additive.
