ActiveCorrosion of metals and alloys -- Evaluation of stress corrosion cracking by the drop evaporation test
金属和合金的腐蚀 滴落蒸发试验的应力腐蚀开裂评价
Application Summary AI generated
This standard specifies the drop evaporation test method for evaluating stress corrosion cracking susceptibility in metals and alloys. It is applied in materials testing and quality control within industries such as aerospace, chemical processing, and power generation, where components are exposed to corrosive environments under tensile stress. The test simulates localized corrosion conditions by periodically applying a corrosive solution to a heated specimen, enabling assessment of material performance in service-like scenarios.
