“…The microstructural alterations brought about by cryogenic treatment, which may include the relocation of solute atoms and the removal of lattice defects, are credited with this enhanced distribution. The better properties shown in cryogenically treated CrMoV steels are anticipated to result from improved chemical dispersion [19,20].…”

The current investigation explores the effect of cryogenic treatment on the microstructural and corrosion behavior of CrMoV low-alloy steels. The casted samples in the required dimensions were treated by annealing followed by deep cryogenic treatment (DCT). Initially, the microstructural modification brought by combined treatments was studied using an optical microscope (OM), scanning electron microscope (SEM), and x-ray diffraction (XRD) technique. After DCT, a refined and uniform grain structure was identified. The DCT resulted in the development of a fine-grained structure and reduced the mean grain size of the alloy, and this refinement of the grain structure is due to the reduction of lattice defects during the cooling process. The corrosion behavior was studied using the weight loss and Tafel polarization tests. The corrosion findings indicated a significant enhancement in the corrosion resistance of the specimens after DCT. The DCT specimens exhibited higher corrosion potentials compared to the base material. The DCT can promote the development of a more protective passive layer on the sample’s surface. This passive layer serves as an obstacle, preventing the diffusion of corrosive products and increasing corrosion resistance. Finally, it suggests that DCT positively impacts the CrMoV steels’ resistance to corrosion.

“…By recording the metallographic structure at different magnification, the corresponding retest time at the highest resolution was obtained. P.Jovičević-Klug [6] studied the different effects of common corrosion agents on the microstructure of alloy steel to determine the most common corrosion agents for Tool steel. Mou Weiping from Shanghai Jiao Tong University [7] used metallographic method to determine the depth of the carburized layer of 20Cr steel after carburization, and analyzed the carbon concentration gradient relationship through metallographic images.…”

20CrMnMo is one of the most widely used alloy steels, and its mechanical properties are closely related to the metallographic structure of the material. Clearly obtaining the distribution pattern of metallographic structure is of great significance for studying the mechanical properties of 20CrMnMo. In this paper, 20CrMnMo samples were subjected to corrosion treatment at different times, and the microstructure of the samples was observed by optical microscope (OM) and Scanning electron microscope (SEM). Through optical microscope observation, the metallographic structure images under different magnification and corrosion time were compared and analyzed, and the best corrosion time interval for metallographic structure observation was obtained; On this basis, by using Scanning electron microscope and EDS, the microscopic images at higher magnification were obtained, and the mechanism of corrosion time on the metallographic structure was further analyzed and explained.
