STRESS CORROSION CRACKING TESTING DEVICE

摘要

The stress corrosion cracking (SCC) testing device includes a corrosion cell for placing a specimen to be tested therein. The corrosion cell is configured to simulate the extreme high temperature and pressure, as well as the corrosive environments experienced by engineered, industrial components. A heating element and a pressurizing assembly are operatively attached to the corrosive cell to simulate the high temperature and pressure environs. A circulation assembly is also attached to the corrosion cell to simulate both flowing and stagnant conditions of the corrosion solution that the industrial component can be subjected to. A loading assembly with a specimen holding shaft is operatively attached to the specimen to place a predetermined and constant tensile load on the specimen until fracture in order to determine K1 and KIscc of the engineered component. PTFE seals are used to seal the specimen holding shaft during testing.
