Abstract

Language:

This study investigates the real-time tomography of stress corrosion cracking on stainless steel using an in-situ corrosion tensile test. The objective is to develop a comprehensive understanding of the corrosion behaviors of thermally sensitized 304 and 20/25/Nb stainless steels. Methodologically, the researchers employed X-ray tomography at a synchrotron beamline to visualize the three-dimensional corrosion progression on the materials with differing surface finishes. Additional analyses were conducted using focused ion beam (FIB) and energy-dispersive spectroscopy (EDS) to explore the connection between corrosion behaviors and the compositions of the affected grain boundaries. Results indicated that real-time imaging allowed for significant insights into the corrosion mechanisms, revealing the distinct responses of the stainless steels under stress. The findings contribute valuable knowledge to the field of materials science, particularly in assessing the integrity and durability of stainless steel materials under corrosive conditions.
