[en] A dynamic straining test has been developed for rapid screening of materials relative to stress corrosion cracking in an accelerated high-temperature aqueous environment. The technique consists of conducting slow tensile tests in an environment of 289⁰C high-purity water with 8 ppM dissolved oxyen. This extremely aggressive environment was used in this investigation to maximize the potential for intergranular stress corrosion cracking. Future correlations in environments of industrial concern are required before full industrial utilization of this technique can be realized. Because of the nature of the environment, the test is conducted in an autoclave assembly using a unique sliding seal arrangement. In turn, the autoclave is connected to a recirculating, water-chemistry controlled loop system. Several applications are discussed to illustrate the use of the test method. In addition, a summary of the various qualification data correlating the dynamic straining test results with longer term constant load test results are presented
