Corrosion behavior of Fe25Mn6Si5Cr shape memory alloys modified with rare earth in a NaCl solution

A question still remains whether the corrosion resistance of such alloys will be deteriorated due to adding RE, which has to be considered when they are used practically, for instance, in water-pipe system. Therefore, the corrosion behavior of the Fe25Mn6Si5Cr based alloys containing various content...

Description
Summary:A question still remains whether the corrosion resistance of such alloys will be deteriorated due to adding RE, which has to be considered when they are used practically, for instance, in water-pipe system. Therefore, the corrosion behavior of the Fe25Mn6Si5Cr based alloys containing various contents of RE in 3.5 wt% NaCl aqueous solution that approximately simulates the sea water was investigated by using potentiodynamic polarization measurement and immersion tests. An 18-8 stainless steel was taken as reference material for comparison.
