“…Such a phenomenon can be attributed to the recrystallization of the extruded materials in the following heat treatments, which can be also confirmed from the EBSD images, especially that of pure Ti materials (Victoria-Hernandez and Yi, 2014). Because of the larger deformation energy stored in the (TiC + TiB)/ Ti composite, the recrystallization temperature for (TiC + TiB)/Ti composite is much lower than that of pure Ti materials.…”

Abstract(TiC p + TiB w )/Ti composite was firstly prepared by spark plasma sintering (SPS) and hot extrusion from Ti-B 4 C system, and then isothermally heat treated at 400-800 °C for 24 h to study the pinning effect of the in situ formed reinforcements. Microstructure and phase composition was investigated by SEM, XRD and TEM, variation of the grain size of Ti matrix was studied by EBSD analysis, and room temperature strength was also measured after different heat treatments. Results show that, comparing with pure Ti materials, both the grain size of Ti matrix and the room temperature strength of the composite almost keep stable after heat treatments, suggesting the pinning effect of in situ formed TiC p and TiB w is effective to suppress the growth of Ti matrix grains during heat treatments.

“…Thus, there is a significant difference in the deformation and recrystallization behavior during tensile testing. To identify recrystallized grains, GOS maps are considered, assuming that recrystallized grains will appear with low orientation spread whereas nonrecrystallized deformed grains do not [19,20]. Grains with GOS< 2° and high angle grain boundaries (HAGB, >15°) are considered.…”

Many studies have shown that textures with less distinct alignment of basal planes and the related improvement of formability are found in alloys that contain rare-earth (RE) elements and zinc. However, the effect of the combination of these additional elements on the texture modification has not been yet clearly understood. In this work, sheet samples from Mg-Zn-RE alloys rolled at 400°C were used for in-situ synchrotron X-rays diffraction measurements under tensile loading at different temperatures, in order to track the development of diffraction profiles and textures during deformation. In Mg-Zn-RE alloys, a significantly retardation of recovery and dynamic recrystallization during the high temperature deformation is observed in comparison to the RE-free Mg-Zn alloy. The differences in the active deformation mechanisms as well as the dynamic recrystallization mechanisms are reviewed with respect to the texture alteration. For discussion of the impact of different mechanisms, EBSD observations reveal the microstructure development.

Abstract:The amplitude-dependent internal friction of continuously-cast and rolled AZ31 magnesium alloy was measured in this study. Samples were annealed and quenched step by step; immediately after the treatment, the amplitude dependence of the logarithmic decrement was measured. Changes in the microstructure due to thermomechanical treatment were reflected in changes in the damping. Internal friction is influenced by the dislocation substructure and its modification due to solute atoms migration, microplastic deformation, and twins' formation. Internal friction in the rolled sheets is affected by the rolling texture.
