Abstract
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.
