Three-dimensional crystal plasticity finite element analysis of microstructure and texture evolution during channel die compression of IF steel

Crystal plasticity simulation of in-grain microstructural evolution during large deformation of IF-steel

“…The lattice rotates due to the shear strain and reaches a preferred orientation based on the loading conditions and the initial orientation of the lattice. There are numerous works devoted to studying the evolution of texture in bcc metals and especially steel [27,45,[49][50][51][52][53][54][55][56][57] . The rolling texture in bcc metals belongs mainly to two families of α (RD 110 ) and γ (ND 111 ) fibers.…”

“…Problems involving the deformation of solid materials are usually formulated in a Lagrangian context, in which the mesh is attached to the deformable body and deforms with a change in the material's shape. As a result, the mesh gets distorted due to the heterogeneity of the deformation [44,45] . When the mesh distortion becomes too large, the simulation fails to converge.…”

Crystal plasticity modeling of grain refinement in aluminum tubes during tube cyclic expansion-extrusion

“…The contours in Figure 7 demonstrate that the deformation is remarkably inhomogeneous mainly because of the interaction among the neighboring grains with different orientations. 6 This heterogeneity in the deformation due to the inhomogeneous intragranular deformation results in inside the grains. These misorientations (orientation gradients) are recognized as a main reason for the grain subdivision and refinement.…”

“…7,8,12 Accordingly, there is orientation gradient inside the grains because of the heterogeneous deformation. 6 Grain 19 is clearly subdivided into subgrains and there is a remarkable orientation range in its pole figure. The orientation spread is also seen for Grain 13, but this spread is isotropic in comparison with that of Grain 19.…”

“…Nowadays, the crystal plasticity Enite element method (CPFEM) which is the single crystal plasticity theory coupled with Enite element method is known as an effective virtual tool for simulating the microstructure evolution during SPD. 6 Nonetheless, to the extent of our knowledge, the crystal plasticity Enite element (CPFE) modeling of the SPD methods is limited to the equal channel angular pressing (ECAP) process. [7][8][9][10][11][12][13][14] Li et al 10 demonstrated the capability of CPFE approach in prediction of the texture formed during ECAP.…”
