چکیده انگلیسی
The effects of temperature on the tensile properties and stress corrosion cracking (SCC) susceptibility of austenitic stainless steels AL-6XN, HR3C, and 316Ti in deaerated supercritical water were studied by performing slow-strain-rate tensile (SSRT) tests. The SSRT tests were carried out in deaerated supercritical water at temperatures of 550, 600, and 650 °C, a pressure of 25 MPa, and a strain rate of 9.26 Ã 10â7 sâ1. The results show that AL-6XN exhibits the highest ultimate tensile strength and yield strength at each temperature, followed by HR3C and then 316Ti. Temperature has a large effect on the tensile properties of each material. The SCC susceptibility of AL-6XN increases with increasing temperature, whereas 316Ti exhibits the opposite trend. The fracture surfaces of all HR3C specimens and the 316Ti specimen tested at 550 °C are dominated by an intergranular fracture morphology, showing the high susceptibility of these specimens to SCC. Transgranular fracture was observed for specimens of AL-6XN strained at 600 and 650 °C.
