Dynamic recrystallization is an important mechanical weakening mechanism during the deformation of ice, yet we currently lack robust quantitative tools for identifying recrystallized grains in “migration” regime that dominates ice at temperatures close to melting point. Here, propose grain boundary irregularity as a means discriminating between (high sphericity, low irregularity) and remnant (l...

In the present study, microstructure characteristic and texture evolution of TB18 titanium alloy were studied by isothermal hot compression under different strain with rate 0.001 s?1 0.1 in ? phase zone. Electron Back-Scattered Diffraction (EBSD) XRD used to characterize macrotexture. Microstructure demonstrated that coarse grains flatten elongated direction as increased. The dynamic recrystall...
