Abstract: In this study, the imaging principles of backscattered electron imaging (BSEI) technique was introduced. The influence of topographic contrast, atomic number contrast and electron channel contrast (ECC) on the BSEI figure was described. The application of BSEI on the research of several kinds of steels, such as torsional deformed 304 stainless steel (characterizing material defects), oxide dispersion strengthened (ODS) steel (characterizing second phase particles) and surface chromized carbon steel (characterization coating), was summarized in detail. The advantages and challenges of the application of BSEI in steels materials research were discussed by using these cases. These findings can serve as a guide for further research of backscattered electron imaging in the field of iron and steel materials.
Key words: applied physics; backscattered electron imaging; 304 stainless steel; ODS steel; Cr coating
