Stress corrosion cracking - Wikipedia
Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to a tensile stress, especially at elevated temperature.
Environmental stress cracking - Wikipedia
Environmental Stress Cracking (ESC) is one of the most common causes of unexpected brittle failure of thermoplastic (especially amorphous) polymers known at present. According to ASTM D883, stress cracking is defined as "an external or internal crack in a plastic caused by tensile stresses less than its short-term mechanical strength".
Stress Corrosion Cracking
2024年7月19日 · Stress corrosion cracking (SCC) is a progressive fracturing that occurs in metals as a result of the combined influence of tensile stress and a corrosive environment. Structural failure due to SCC can be very unpredictable—failure could occur after as little as a few hours of exposure, or the equipment could continue to function normally for ...
What is Stress Corrosion Cracking (SCC)? Mechanism and Prevention …
In the steel industry, stress corrosion cracking (SCC) is a form of intergranular corrosion that results in crack formation in a corrosive environment. As steel is the most common industrial material, stress corrosion cracking poses a significant threat to industrial systems such as pipelines, power plants, chemical industries, bridges, and so on.
Stress Corrosion Cracking - an overview | ScienceDirect Topics
Stress corrosion cracking (SCC) describes the initiation and growth of cracks caused by the synergistic combination of a nominally static, or slowly increasing, tensile stress, and an environment, which is usually corrosive. The stresses are typically below the macroscopic yield strength but sufficient to induce localized microscopic plastic ...
The Materials Analyst, Part 23:Stress cracking: How to avoid this ...
1999年8月14日 · As little as 10 percent glass fiber can reduce problems with stress cracking in materials like polycarbonate and polysulfone. And finally, as is the case with so many properties, molecular weight is critical. The higher molecular weight materials will resist stress cracking for much longer and at higher critical stress levels.
Stress corrosion cracking: characteristics, mechanisms and …
2017年7月21日 · The cracking of a metal alloy will sometimes result from the combined action of a corrodent and tensile stress, and this phenomenon is called stress corrosion cracking (SCC). Stresses that cause cracking can be residual or may be applied during service.
Stress Corrosion Cracking - an overview | ScienceDirect Topics
Stress corrosion, also commonly called stress corrosion cracking (SCC), results from the combined action of mechanical stress, such as static or applied tensile stress, and a corrosive environment [90].
Stress corrosion cracking (SCC) in stainless steels
2011年1月1日 · Stress corrosion cracking (SCC) is the brittle failure at relatively low constant tensile stress of an alloy exposed to an environment. A synergistic action of corrosive environment and tensile stress on the material is required to cause SCC.
