EBSD characterization of recrystallization microstructure of cold-swaged Ti-23Nb-0.7Ta-2Zr-O alloy GUO Wen-yuan(郭文渊), SUN Jian(孙坚), LI Xiao-ling(李晓玲), WU Jian-sheng(吴建生) School of Materials...> Abstract: The microstructures of the cold-swaged and recrystallized Ti-23Nb-0.7Ta-2Zr-O (TNTZO) (mole fraction, %) alloy were investigated by electron backscatter diffraction (EBSD). The difference......
-swaged and the annealed TNTZO alloy were investigated by transmission electron microscopy(TEM) to study the recovery of the cold-swaged TNTZO alloy. The results show that no dislocation can be distinguished from the cold-swaged TNTZO alloy due to the heavily-accumulated strains, whereas high density dislocations were observed in the cold-swaged TNTZO alloy after annealing at 800 ℃ for 5 min. During......
cold-swaged and annealed condition were investigated by electron back-scattering electron diffractometry (BSD). The results show that the microstructures of Ti-23Nb-0.7Ta-2Zr-1.2O alloy deformed contain high density low angle grain boundaries, the alloy has distinctive <110> fiber texture paralleling the axial direction of stick. During annealing of the cold-swaged alloy, the low-angle......
