%X Localized corrosion of Scalmalloy® processed by Selective Laser Melting (SLM) under certified conditions is
studied and correlated with the intermetallic particles present in the microstructure. Two types of samples are
considered: as-built and heat-treated samples. The heat treatment does not modify the pitting corrosion per-
formance. All samples exhibit two groups of pits with different repassivation behaviour. Si-bearing and Fe-
bearing phases produce pitting, while Al(Sc,Zr) is not found to be important. The two types of samples are
resistant to intergranular corrosion (IGC) according to ASTM G67 thanks to the low content of β phase. However,
the heat-treatment slightly increases the IGC-susceptibility.
