Abstract
Effects of temperature on ratchetting behavior and cracking mechanism of 316LN stainless steel in different temperature pressured water environments were studied. The results indicated that there was a threshold for the influence of water temperature on ratchetting life. When water temperature was lower than 100 ℃, the water temperature had little effect on ratchetting life, the ratchetting cracking mechanism was dominated by cyclic hardening. When water temperature was increased to 100 ℃ - 325 ℃, the slip-dissolution mechanism dominated the ratchetting cracking, and the ratchetting life was a power function relationship with water temperature, i.e., N = Nair(T/100)−0.183.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
