ABSTRACT： New alloys are being developed for advanced applications and a
number of properties needs to be investigated before such alloys can be put in use for

a given application. In this work, the electrochemical behavior of a newly developed

high manganese transformation induced plasticity (TRIP) steel Fe39Mn20Co20Cr15
Si5Al1 (at.%) consisting of y and £phases in 3.5 wt.% NaCl solution at room

temperature was studied. The linear dynamic polarization test demonstrated corrosion

photoelectron spectroscopy was used to characterize the chemical make-up of

passivation film. Further experiments are underway for detailed surface
characterization.
