Abstract

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.

热处理对冷轧复合cu基合金电化学腐蚀行为的影响

研究了热处理温度和保温时间对冷轧复合铜基合金组织和耐蚀性的影响。在500℃下，随着保温时间的增加，合金中的偏析先减少后增加。当温度升高到600℃时，晶粒形成等轴组织。当保温温度达到700℃时，等轴晶粒尺寸进一步增大，且随着保温时间的延长晶粒尺寸逐渐增大。当温度低于600℃时，合金的耐蚀性随保温时间的增加而提高，其顺序为：90 >；150比;当保温温度增加到700℃时，耐蚀性随保温时间的延长而降低。cu基合金耐蚀性能的变化主要是由于热处理过程中化学成分和组织分布的变化所引起的电位差。
