L The cellular automata (CA) methodology is applied to the case of intergranular corrosion. Appropriate CA rules are generated which can reproduce and predict the advance of a corrosion front. The proposed model shows qualitative and quantitati...

Statistical Modeling of Minimum Intergranular Corrosion Path Length in High-Strength Aluminum Alloy

Corrosion Kinetics

This Module consists of ten Web pages of required reading. The pagination is visible at the bottom of each page with direct links to adjacent pages. Introduction Thermodynamic principles can help explain a corrosion situation in terms of the stability of chemical species and reactions associated with corrosion processes. However, these principles cannot be used to predict corrosion currents or ...

Intergranular pitting corrosion of CoCrMo biomedical implant alloy.

CoCrMo samples of varying microstructure and carbon content were electrochemically corroded in vitro and examined by scanning electron microscopy and electron backscatter diffraction techniques. The rate of corrosion was minimized (80% reduction from icorr = 1396 nA/cm(2) to icorr = 276 nA/cm(2) ) in high-carbon CoCrMo alloys which displayed a coarser grain structure and partially dissolved sec...

Effects of irradiation on intergranular stress corrosion cracking

Intergranular stress corrosion cracking &YSCC) is a pervasive and generic problem in current light water reactor and advanced reactor designs that can lead to widespread component failure. IASCC is believed to be due to either to changes in the grain boundary composition, the microstructure or the water chemistry and corrosion potential. Of greatest interest are the changes in composition and m...
