- Abstract:
- In order to explore the variation of grain orientation during the flattening of cylindrical wire, the evolution of the texture of the experimental sample after the secondary treatment of ECAP by asynchronous rolling was studied with the help of XRD texture diffractometer and three-dimensional orientation distribution function (ODF) analysis. The experimental results show that from the fast roll side, the texture orientation density along the thickness of the cold-rolled experimental specimen from the surface layer to the center layer increases with the increase of deformation variables, and the main texture components in the cold-rolled pure iron specimen gradually form a α-fiber texture of <110>//RD (rolling direction) and a γ-fiber texture of <111>//ND (rolling face normal), and the orientation density level of the texture components gradually increases. In addition, through the analysis and quantitative calculation of the reverse polar diagram, it can be seen that the volume fraction of the <110 > texture components shows an increasing trend from the table to the inside under different pressures. < the volume fraction of the 100 > texture components rises first and then decreases from the surface to the inside when the amount is 0%, and 40%. When the amount of pressure down is 80%, the opposite trend occurs. When the amount of pressure is 0%, the volume fraction of the <111 > texture components first decreases and then increases. However, when the indentation amount is 40%, when the amount is 80%, the <volume fraction of the 111 > texture component shows an upward trend, and there is a certain difference along the thickness of the sample.
