- Abstract:
- In order to explore the cold deformation microstructure and texture of the precipitated steel, the conformed steel with severe plastic deformation was subjected to certain heat treatment to obtain cementite samples of a certain shape and submicron size, and then the above samples were rolled with different deformation variables to obtain the analysis samples of microstructure and texture, and the microstructure and deformation texture of the rolled samples were analyzed by field emission scanning electron microscopy (FE-SEM) and texture diffractometer (XRD). The results show that the annealing of cold-rolled high-carbon steel shows that the number of lamellar cementite decreases and the number of granular cementite increases, forming a complex microstructure sample in which two shapes of cementite and ferrite coexist. During the cold rolling process, the ferrite grains are elongated and gradually develop into fibrous; The grain size and shape of cementite do not change much, and the distribution is relatively uniform. With the increase of deformation variables, the main textures in the co-analysis steel gradually formed a α-fiber texture consisting of <110>//RD (rolling direction) and γ-fiber texture of <111>// ND (rolling face normal), and the grain orientation gradually gathered to the main texture component types such as {558}<110> and {001}<110>.
