Strain-induced microstructure evolution, including grain refinement of ferrite and <span style=\"color:red\">cementite</span> as well as dissolution of <span style=\"color:red\">cementite</span>, was examined using transmission electron microscopy. Upon straining, dense dislocation walls were developed in ferrite grains, which evolved gradually into sub-boundaries and highly misoriented grain boundaries (GB) at increasing strains, leading to grain refinement of the ferrite. The ferrite refinement process is greatly facilitated by the presence of dispersed <span style=\"color:red\">cementite</span> particles, as the <span style=\"color:red\">cementite</span>/ferrite interfaces are effective nucleation sites for dislocations and also barriers for dislocation motions. When ferrite grains are refined to sizes smaller than that of <span style=\"color:red\">cementite</span> particles, plastic deformation occurs in <span style=\"color:red\">cementite</span> particles, characterized by edge dislocation gliding along the I I 10) and I 10 0) planes. Dislocation gliding in <span style=\"color:red\">cementite</span> is initiated at intersections of the <span style=\"color:red\">cementite</span>/ferrite interfaces and ferrite GB. Accumulated multiple gliding progressively refines <span style=\"color:red\">cementite</span> into nano-sized <span style=\"color:red\">cementite</span> particles mixed within ferrite nano-grains in the top surface layer. A decreasing volume fraction of <span style=\"color:red\">cementite</span> is observed with decreasing depth in the top deformed layer, indicative of dissolution of <span style=\"color:red\">cementite</span> induced by increased plastic straining.
