摘要：

The effect of carbon content on microstructure, texture and hydrogen permeation behavior of an ultra-low carbon Ti-bearing steel for enameling was investigated by means of transmission electron microscope (TEM), electron backscattered diffraction (EBSD) test and electrochemical hydrogen permeation experiment. It was found that the strength of the annealed steel sheets increases with the increasing carbon content, but little difference for the n value; the elongation and r value show a trend of decrease with the increase of carbon content; corresponding to the r value, the γ-fiber texture of the annealed steel sheets was weakened gradually with the increase of carbon content. The hydrogen diffusion coefficient, DL decreases with the increasing of carbon content, when carbon content below 0.004%, DL is lower than the critical value, thereby the fish-scaling resistance for the steel sheet cannot be guaranteed for the enameling process. © All right reserved.
