1.	What is Intergranular corrosion?(a) Localized attack at the grain boundaries(b) Localized attack at the grain faces(c) Uniform attack on grains(d) Localized attack at and adjacent to the grain boundariesI have been asked this question during an interview.I'm obligated to ask this question of Eight Forms topic in chapter Eight Forms of Corrosion of Corrosion Engineering
Answer» The correct option is (d) LOCALIZED attack at and adjacent to the grain boundaries The best explanation: Intergranular CORROSION MEANS corrosion in between two or more GRAINS. Intergranular corrosion is a localized attack at and adjacent to the grain boundaries.
