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... in microstructure, texture and recrystallization process was evaluated between the TNTZO alloy and traditional body centered cubic (bcc) metals. The results show that the cold-swaged TNTZO alloy presents......
properties in both the cases were studied. Static shear strength of refilled weld samples was found to be better than those welded by conventional FSSW process at all tool rotational speeds... was measured in the HAZ. Key words: AA6061-T6 Al alloy; friction stir spot welding; FSSW-FFP; static shear strength 1 Introduction In recent years, aluminum alloys have attracted attention of many researchers......
softening due to dynamic recrystallization and work hardening, the curves drop to a steady-state region.

Trans. Nonferrous Met. Soc. China 22(2012) 1866-1871 Formation of precipitates and recrystallization resistance in Al-Sc-Zr alloys JIA Zhi-hong1,2, Jostein R?YSET3, Jan Ketil SOLBERG2, LIU Qing1 1.... The recrystallization resistance of samples that was 90% cold rolled and isothermal annealed for half an hour in the temperature range of 200-600 ℃ was investigated. The results show......
on the mechanism of dynamic recrystallization (DRX) was discussed. The results show that, with increasing deformation temperature and decreasing strain rate, the content of δ phase decreases, but the grain size and volume fraction for dynamic recrystallization increase. The plastic deformation is mainly accommodated by bending, kinking and shearing of δ phase. Under the drive force of reduced interface......
