Crack propagation kinetics under asymmetric cyclic loading for 316LN SS in high-temperature solution
Publikováno v:
Journal of Materials Research and Technology, Vol 32, Iss , Pp 2115-2126 (2024)
Crack propagation rates (CPRs, or da/dN) of 316LN stainless steel (SS) in high-temperature solution under asymmetric cyclic loading conditions are experimentally determined, focusing primarily on the effect of load-rise time on crack propagation. The
