← ScienceWhich outcome decreases ductility during metal chloride electrolysis?
A)Grain boundary segregation impurities✓
B)Increased cathodic current density
C)Formation intermetallic brittle compounds
D)Elevated electrolyte bath temperature
💡 Explanation
Grain boundary segregation causes reduced ductility because impurities form and weaken metallic bonds through ionic interactions. Therefore ductility drops at boundaries rather than through bulk deformation because segregation effects dominate rather than thermal diffusivity.
