“…Various investigations [15][16][17][18][19][20][21][22][23][24][25][26] have employed characterization tools like X-ray, neutron, synchrotron, and electron backscatter diffraction (EBSD) to study texture and microstructure evolution in the individual phases of two-phase materials. Finite element methods and self-consistent simulations [8,[13][14][15][16][17][18][19] have been used to elucidate the deformation behavior of these materials. Lebensohn et al [16] modeled the rolling texture evolution in two-phase (a + b) titanium alloys using a 2-site VPSC formulation that consisted of solving a two inclusion problems as against a single inclusion problem for 1-site VPSC simulations.…”

Deformation texture evolution in two-phase xFe-yNi-(100-x-y)Cr model alloys and Ti-13Nb-13Zr alloy was studied during rolling to develop an understanding of micro-mechanisms of deformation in industrially relevant two-phase FCC-BCC steels and HCP-BCC titanium alloys, respectively. It was found that volume fraction and contiguity of phases lead to systematic changes in texture, while morphology affects the strength of texture. There was a characteristic change in texture from typical Brass-type to a weaker Copper-type texture in the austenite phase accompanied with a change from alpha fiber to gamma fiber in ferrite phase for Fe-Ni-Cr alloys with increase in fraction of harder ferrite phase. However, similar characteristic texture evolution was noted in both a and b phase irrespective of the different initial morphologies in Ti-13Nb-13Zr alloy. Viscoplastic self-consistent simulations with two-phase scheme were able to qualitatively predict texture evolution in individual phases. It is proposed that the transition from iso-strain-type behavior for equiaxed microstructure at low strain to iso-stress-type behavior at higher strain is aided by the presence of higher volume fraction of the second phase and increasing aspect ratio of individual phases in two-phase alloys.

“…Rotation and tilt as done for Figure 4c The texture of the Mg-Mg 2 Si sample after 1 pass is nearly identical to that for pure Mg. Due to the Mg 2 Si particles in this composite the orientation density (texture sharpness) is weaker. This effect is well known from many investigations of composites with a hard phase in a soft matrix [10]. One important difference is that the deviation from the monoclinic pole figure symmetry is different.…”

Crystallographic texture includes much information on a material’s behaviour that depends on the processed material itself, the particular thermomechanical processing it has undergone, and the quality of the process. ECAP processed pure Mg and Mg alloys were characterised by their texture and are discussed in terms of texture symmetry. For all types of deformation, including ECAP, the basal plain orientation has to follow certain general rules. Particularly for larger number of passes the ECAP texture can be explained in terms of standard rolling or extrusion textures.

“…One important result is the increase in strength of the deformation processed composite, which is believed to be related to, among other factors, the influence of texture on the deformation behavior [4]. In systems combining Al with Cu, Ti or Pb, it was found that the Al phase develops a <111> and <001> double fiber texture in the extrusion direction (ED) when the texture over the whole cross-section is measured [5]. On the other hand, in rectangular extruded material of Al-Ti, Al-Nb and Al-Ni, Al shows four main ideal orientations {123}<643>, {112}<111>, {100}<001> and {110}<111>.The study of highly anisotropic and inhomogeneous materials such as two-phase composites is very important for a basic understanding of many technological materials.…”

By applying cold extrusion, an elemental metal powder composite Al60Mg40 was prepared. The texture gradient was measured over the cross-section of the extrusion profile using synchrotron radiation while the bulk texture was obtained by neutron diffraction. The aluminum phase shows a typical texture component of plane-strain deformation in the middle part of the sample and a uniaxial deformation texture at the surface. In the central region of the extruded bar, the (0002) Mg pole figure shows a split along the extrusion direction (±ED), which also has been observed in rare-earth containing magnesium alloys. These two poles twist towards the transverse direction on moving towards the surface of the extruded bar; one pole moves to +TD and the other one to −TD. The angle of twist increases towards the TD surface.
