We describe an investigation of microstructure in pure nickel (Ni) after cathodic charging in an aqueous electrolyte. Intergranular corrosion occurs on the sample surface and takes the form of long trenches along coherent twin boundaries (CTBs): sites that have often been considered especially resis...
