摘要
对6种不同硫含量的Cu-Ni合金进行了室温拉伸试验。系统地研究了拉伸速率和硫含量对材料屈服强度、拉伸强度、伸长率和断面收缩率的影响。通过扫描电镜、能谱分析和金相组织分析,研究了硫含量对金相组织的影响。分析了Cu-Ni合金中硫析出物的分布、变形及对塑性的影响规律。分析了材料发生断裂的起源和过程及硫含量对塑性影响的根本原因,为后续冷变形过程提供理论依据。
Six kinds of Cu-Ni alloys with different sulfur contents were investigated at room temperature for tensile properties. The effects of tensile rate and sulfur content on the yield strength, tensile strength, elongation, and reduction of area of the alloys were studied. The changes of metallographic structure with sulfur content were studied by scanning electron microscope(SEM), energy disperse spectroscopy(EDS) and metallographic structure analysis. The distribution and deformation of sulfur precipitate and the influence law for the plasticity of Cu-Ni alloy were analyzed. The origin and occurrence of alloy fracture process and the influence mechanism of sulfur content on plasticity were analyzed, providing a theoretical basis for subsequent cold deformation process.
