摘要：
Immersion tests and potentiodynamic polarization measurements were conducted in 1 M sulfuric acid solution (H2SO4) at ambient temperature (similar to 25?degrees C) to investigate the corrosion behavior of CuCrFeNiMn alloy system. The results show that the alloys display a good general corrosion resistance that is mainly influenced by the Cu content and elemental segregation degree. The corrosion resistance degrades when increasing Cu content and elemental segregation degree. Among the tested alloys, the CuCr2Fe2Ni2Mn2 alloy with low Cu content and elemental segregation degree displays a better general corrosion resistance. On the contrary, the Cu2CrFe2NiMn2 alloy with high Cu content and elemental segregation degree exhibits the worst general corrosion resistance.
