چکیده انگلیسی
A study of the annealing behavior of nano-layered steel produced by heavy cold-rolling of lath martensite has been conducted. The results show that the nano-layered structure of lath martensite was stable until annealing at 623Â K for 3.6Â ks. Subsequently, discontinuous recrystallization began in some regions after 673Â K annealing and finished after 873Â K annealing. The nano-layered structure in the specimens annealed for 3.6Â ks at 673-773Â K changed into the multiphase nano-structure composed of equiaxed ferrite grains and carbides. Furthermore, the phenomenon of fracture delamination was observed from the tension fractures of the specimens as-rolled and annealed up to 773Â K for 3.6Â ks. In addition, the mechanisms of structure stability and mechanical behavior are also discussed.
