14b show that Cu and Sb were enriched in the inclusion region. However, the segregation of elements at the grain boundary reduced the surface energy of the grain boundary, and the impact toughness of the steel decreased significantly23. Balanced half-reactions are well tabulated in handbooks and on the web in a 'Tables of standard electrode potentials'. After the surface of the inclusion was thinned, the observation of secondary polishing was carried out; the results showed that the corrosion characteristic products of the inclusion, as shown in Fig. 4d, there were defects or high internal stresses in the pearlite region, and the stress distributions in the grain boundary and intragrain region were uniform.
