Corrosion tests lasting up to 15 000 h have demonstrated that the …
WebFeb 3, 2012 · Intercrystalline corrosion (ICC) is one of the most critical forms of local corrosion for steels and alloys, causing selective breakdown along grain boundaries, as a result which there is loss of alloy strength and ductility and premature failure of a structure. ICC is observed for many corrosion-resistant steels and alloys. WebIntergranular Corrosion. The microstructure of metals and alloys is made up of grains, separated by grain boundaries. Intergranular corrosion is localized attack along the grain boundaries, or immediately adjacent to grain boundaries, while the bulk of the grains remain largely unaffected. This form of corrosion is usually associated with ...
WebApr 3, 2024 · Intergranular corrosion This type of corrosion selectively affects the grain boundaries of the metal or alloy, without causing significant erosion of the grains or crystals. It results in a sharp reduction of the material’s mechanical properties, leading to structural damage or failures. WebAbstract Intercrystalline corrosion (IC) is preferential attack along grain boundaries into the interior of polycrystalline metaUic materials. Intracrystalline corrosion is preferential attack into grains, along subgrain boundaries, or stacking fault planes, or other crystallografic irregularities. Keywords Boundary Zone Chromium Depletion
