RELATION BETWEEN ELECTROCHEMICAL REACTIVITY AND STRUCTURE OF GRAIN BOUNDARIES CORRELATED TO INTERGRANULAR SULFUR SEGREGATION IN ULTRA PURE NICKEL

Résumé

In a ultra pure nickel doped with 8 and 16 ppm of sulfur, we have determined the kineticsand equilibrium state of segregated sulfur at grain boundaries by electrochemical corrosion test. The undoped nickel and the highest segregated specimen are observed in transmission electron microscopy in order to correlate the structural histogram with electrochemical reactivity study and analytical scanning transmission electron microscope experiments.
