Stress Corrosion Cracking of Aluminum Alloys

Stress-corrosion cracking in aluminum alloys is characteristically intergranular.According to the electrochemical theory,this requires a condition along grain boundaries that makes them anodic to the rest of the microstructure so that corrosion propagates selectively along them.Stress Corrosion Cracking Behavior of Materials IntechOpenApr 08,2019 Title A study on stress corrosion cracking of fine grain#0183;Stress corrosion cracking is a phenomenon associated with a combination of tensile stress,corrosive environment and,in some cases,a metallurgical condition that causes the component to premature failures.The fractures are often sudden and catastrophic,which may occur after a short period of design life and a stress level much lower than the yield stress.Stress Corrosion Cracking Behavior of Materials IntechOpenApr 08,2019 Title A study on stress corrosion cracking of fine grain#0183;Stress corrosion cracking is a phenomenon associated with a combination of tensile stress,corrosive environment and,in some cases,a metallurgical condition that causes the component to premature failures.The fractures are often sudden and catastrophic,which may occur after a short period of design life and a stress level much lower than the yield stress.

Stress Corrosion Cracking - NACE

Chloride stress corrosion is a type of intergranular corrosion and occurs in austenitic stainless steel under tensile stress in the presence of oxygen,chloride ions,and high temperature.It is thought to start with chromium carbide deposits along grain boundaries that leave the metal open to corrosion.Stress Accelerated Grain Boundary Oxidation (SAGBO) in Many of these superalloys have been found to suffer from a unique damage mechanism called stress accelerated grain boundary oxidation (SAGBO) cracking.SAGBO is a subclass of stress corrosion cracking that is caused by the synergistic effect of tensile stress (either residual or applied),temperature,and the presence of oxygen.Stress Accelerated Grain Boundary Oxidation (SAGBO) in Many of these superalloys have been found to suffer from a unique damage mechanism called stress accelerated grain boundary oxidation (SAGBO) cracking.SAGBO is a subclass of stress corrosion cracking that is caused by the synergistic effect of tensile stress (either residual or applied),temperature,and the presence of oxygen.
