Influence of Heat Treatment on Electrochemical Corrosion Behavior of Cold Rolled Complex Cu-Based Alloy
The effect of heat treatment temperature and holding time on microstructure and corrosion resistance of the cold rolled complex Cu-based alloy was investigated. Increasing holding time under 500°C, the segregation in the alloy was decreased firstly and then increased. An equiaxed grain structure was formed when the temperature was increased to 600°C. When the temperature was researched to 700°C, the equiaxed grain size was further increased and increasing with the increase of the holding time. When the temperature was below 600°C, the corrosion resistant of the alloys were increased with the various of the holding time following the order: 90 > 150 > 30 min. Increasing the temperature to 700°C, the corrosion resistant was decreased with the increase of holding time. The variation of the corrosion resistant of the Cu-based alloys was mainly due to the potential difference which was induced by the variation of distribution of chemical composition and microstructure during the heat treatment.
