WitrynaStress corrosion cracking (SCC) is a catastrophic type of failure caused by the simultaneous presence of tensile stress and a corrosive environment. During SCC, … Witryna7 sie 2024 · Stress corrosion cracking (SCC) studies were conducted for two FeCrAl alloys (APMT and C26M) in typical simulated boiling water reactor conditions at 288°C containing either dissolved hydrogen or oxygen. Crack propagation studies showed that both ferritic FeCrAl alloys were resistant to SCC at stress intensities below 40 MPa√m.
WitrynaStress corrosion cracking(SCC) is defined as the growth of cracks due to the simultaneous action of a stress (nominally static and tensile) and a reactive environment [1]. SCC is the result of the combined and synergistic interactions of mechanical stress and corrosion/oxidation reactions [2].
