应力腐蚀破裂试验(Stress corrosion Cracking test) 评价材料应力腐蚀敏感性的金属腐蚀 试验方法。 应力腐蚀试样类型有光滑试样和带缺口试 样、预裂纹试样。 应力腐蚀的加载方式有: (1) 恒变形法。 它是通过给试样一定的变形来达到加载的目的, 其裂纹扩展速度随裂纹的扩展而减小。 根据不同情况采 用二点、 三点、...
Stress corrosion cracking Stress corrosion cracking (SCC) is the unexpected sudden failure of normally ductile metals or tough thermoplastics subjected to a
The combined effects of stress and corrosion can cause a special type of failure known as Stress Corrosion Cracking (SCC). This arises under specific circumstances for a given alloy: specific alloy condition, plus specific corrosive media, and sufficient local tensile stress. Chloride induced crackin...
Stress Corrosion CrackingWanhill, R.J.HByrnes, R.TSmith, C.L
What causes stress corrosion cracking?Stress corrosion cracking results from the conjoint action of three components: (1) a susceptible material; (2) a specific chemicalspecies(environment) and (3) tensile stress. For example, copper and its alloys are susceptible to ammonia compounds, mild steels...
