Mengcheng Zhou, Xinfang Zhang. Optimization of <001> grain gene based on texture hereditary behavior of magnetic materials[J]. J. Mater. Sci. Technol., 2020, 38: 1-6.
Fig. 1. Texture of the 66.7% deformed, initially finished Goss-oriented material. (a) and (b) Electron backscattered diffraction IPFZ (Inverse pole figure Z) maps show microstructure of cold-rolled specimen. (c) Orientation distribution function (ODF) of EBSD data are displayed in a φ2 = 45° section. (d) Polar figure and inverse polar figure both represent that the texture component with the highest intensity is {111}<112> component. In addition, a weak Goss component is observed, with a texture intensity of about 0.7.
Fig. 2. Micro-texture under different treatment conditions. IPFZ maps of (a) and (b) conventional heat treatment for 5 min and (c) and (d) electric pulse treatment for 5 min. The sample treatment temperature is (a) and (c) 680°C and (b) and (d) 800°C. Boundaries with misorientations larger than 15° are superimposed as black lines and 5°-15° are white.
Fig. 3. The difference in Goss-orientation distribution function and volume fraction of Goss grain by electropulsing treatment (EPT) and traditional heat treatment (THT). (a) Goss-orientation distribution with treated temperature for 5 min by EPT and THT. (b) The volume fraction of Goss grain with treated temperature for 5 min by EPT and THT. (c) ODF and Polar figure after 800°C for 5 min by THT. (d) ODF and Polar figure after 800°C for 5 min by EPT. (e) Misorientation angle distributions of samples after 800°C for 5 min by EPT and THT.
Fig. 4. Effects of temperature and time on Goss-texture under two conditions. (a)-(c) and (d)-(f) EBSD of cold-rolled specimen treated at 750°C for 2 min by EPT and 1200°C for 2 h by THT, respectively. (g) The orientation distribution function and the volume fraction of Goss-texture.
