Excess Volume in Grain Boundary Segregation
2014
Journal of Surface Analysis
Preserved Fulltext
Segregation volume is an important quantity controlling the pressure effect on grain boundary chemistry. In the present paper, we define molar segregation volume on basis of fundamental thermodynamics and evaluate it for example of phosphorus and sulfur grain boundary segregation in low-alloy ferritic steels including its development during non-equilibrium segregation under tensile and compressive deformations. We also show expected effect of anisotropy on equilibrium segregation under
