Influences of Rare Earth Y Contents on Microstructure and Properties of B10 Copper Alloy

摘要

    摘要
  • 摘要: 用中频真空感应炉制备了不同钇含量的B10铜合金,利用光学显微镜、扫描电镜、拉伸试验机、维氏硬度计和电化学工作站等研究了稀土钇含量对合金显微组织、力学性能和耐腐蚀性能的影响。结果表明:微量稀土钇可显著细化晶粒,提高合金的强度和硬度;随钇含量增加,合金的晶粒尺寸先减小后略有增大,强度和硬度先增大后略降低,塑性则变化不大;添加微量稀土钇后,腐蚀表面膜和B10铜合金基体的结合力增强,耐腐蚀性能得到提高;随稀土钇含量增加,合金的冲刷腐蚀速率先降低后略升高,电荷转移电阻Rt和氧化膜层电阻Rf均先增加后有所降低。
    Abstract: B10 copper alloys with different Y contents were prepared in vacuum mid-frequency induction furnace. The influences of Y contents on microstructure,mechanical properties and corrosion resistance of the alloy were studied by optical microscopy,scanning electron microscopy,tensile testing,Vickers hardness testing and electrochemical testing. The results show that Y could significantly refined the grain and increased tensile strength and hardness of the alloy. The grain size first decreased and then increased a little,the strength and hardness first increased and then decreased a little,the plastic changed little with the increase of Y contents. The adhesive force between the surface film and the B10 copper alloy matrix increased,the corrosion resistance was improved by a trace addition of rare earth Y. With the increase of Y content,the erosion corrosion rate first decreased and then increased a little,the charge transfer resistance Rt and the film resistance Rf first increased and then decreased a little.
