Abstract
The effect of the aging time at 500â¯Â°C on the microstructure evolution and electrochemical behaviour of 15-5PH ultra-high strength martensitic stainless steel is presented. The results show that Cu-rich clusters and (Cu, Nb)-rich nanoparticles are observed from 1â¯min to 240â¯min. The aging time influences the pitting resistance and semiconductive behaviour of the passive film in a chloride solution. The disappearance of Cu species in the passive film after 240â¯min is attributed to the precipitation of Cu-rich nanoparticles. Moreover, the variations in the Cr/Fe ratio and dehydration effect with the aging time are discussed.
