Abstract

In this work, the influence of reversed austenite on the intergranular corrosion of AM355MSSs (martensitic stainless steels) was investigated. The combined results revealed that the reversed austenite exhibited an inhibiting effect on the intergranular corrosion of AM355MSSs. The inhibiting effect of reversed austenite on the intergranular corrosion was summarized as follows. Firstly, the formation of reversed austenite at the Cr-depleted regions reduced the number of nucleation sites for intergranular corrosion. Secondly, the reversed austenite always distributed along the martensite lath boundaries, preventing the propagation of intergranular corrosion.
