Microstructure Evolution of Commercial Pure Titanium During Interrupted In Situ Tensile Test
نویسندگان
چکیده
Microstructure evolution of commercial pure titanium is investigated by interrupted in situ electron backscatter diffraction (EBSD) measurement during tensile deformation along transverse direction at room temperature. After 24 pct elongation, the split basal texture initial material weakened and rotated around 90 deg normal (ND). $${{11}\bar{2}{{2}}}$$ - $${{10}\bar{1}{{2}}}$$ double twin main reason for change texture. The poles are nearly perpendicular to ND primary back through reorientation secondary twin. Both Schmid factor criterion displacement gradient accommodation considered predict twin-induced TD tension. Kink bands formed accumulation 〈a〉 dislocations also observed deformed grain. activation other slip systems can deviate rotation axis reduce angle kink boundary. Besides, boundary with high dislocation density obviously hinders transmission simultaneously be taken as a preferential nucleation site

Microstructure Evolution during Tensile Deformation of a Nanostructured Bainitic Steel
In situ neutron diffraction experiment was used during tensile testing at room temperature to examine the changes on the percentage and texture of both ferrite and austenite in a nanocrystalline bainitic steels transformed at two different temperatures 200°C and 300oC for different times to achieve the same phase percentages. Both samples showed an inadequate capability of austenite to transfor...

The quantitative characterization of the microstructure evolution in high-Mn steel during deformation is of great importance to understanding its strain-hardening behavior. In the current study, in situ high-energy synchrotron X-ray diffraction was employed to characterize the microstructure evolution in a Fe-17Mn-1.5Al-0.3C steel during a tensile test. The microstructure at different engineeri...

متن کاملMicrostructure and microtexture of highly cold-rolled commercially pure titanium
The microstructure and texture evolution of a commercially pure titanium sheet during cold-rolling is investigated in detail by X-ray diffraction and by orientation imaging in the FEG-SEM and in the TEM. The experimental data are compared with simulation results obtained by a viscoplastic self-consistent model. The aim of this work is to provide with a detailed description of the fine scale def...
