    Citation Excerpt :

    Cementite is brittle and hard at room temperature due to covalent bonding, and is therefore difficult to deform plastically [43]. It is usually quite free of dislocations and sub-boundaries [44,45]. As a result, the majority of the dislocations exist in the ferrite phase.

    Citation Excerpt :

    Cementite may nucleate and grow along the (112) twin plane of ferrite or martensite due to the low surface energy in the tempering process [45,46]. Planar and stacking defects of cementite have been reported in some steels [47–49]. However, twins in cementite are rarely observed and characterized by TEM.

    This was specifically studied by Keh [34], who stated that gross deformation of the cementite was found during plastic deformation of 1095 steel at elevated temperatures when using light optical microscopy. Keh [34] reported that some of the spheroidised cementite had been severely elongated to a/b values as high as 10. Comparable observations were made by Zhou et al. [35] who studied the microstructural evolution of AISI 52100 steel in soft-annealed condition subjected to severe plastic deformation induced by surface mechanical attrition treatment (SMAT).
