摘要
通过建立CuCr合金中晶粒尺寸影响饱和蒸气压进而影响截流值的热力学模型,从理论上初步探讨了CuCr合金中组织细化降低截流值的规律。指出触头材料显微组织细化和超细化,是降低CuCr合金截流的一种重要手段。
In this paper, a thermodynamic model has been established which deals with the influence of Cr particle size in CuCr vacuum contact alloys on satu-rated vapor pressure and chopping current, and indicates that the refinement of grain size is an important method to reduce chopping current for CuCr alloys.
