LAMELLAR TEARING AND HIC OF THE THICK LOW-CARBON STEEL PLATES
The phenomenon of the formation of the lamellar tearing in banded low-carbon steel plates has been studied. In this study, the specimens were divided into two parts by the technique of NDT (Non-destructive Testing), which was called NDT-UQ and NDT-Q. To determine the probability of HIC with respect to the direction of banding, hydrogen charging of the NDT-Q specimens in a H2S saturated saline solution was performed. After the specimens had been charged for 96h, a detailed micro-structural investigation assisted by the OM and SEM technique was used for checking the morphologies and propagation paths of HIC. Compared with the research of the NDT-UQ specimens, the results show that the hydrogen is not the chief factor which leads to the lamellar tearing of the banded low carbon steel.
