摘要
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 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 a pronounced 〈110〉fiber texture in the axial direction. The recrystallization of the TNTZO alloy is achieved by the nucleation of new grains and the growth of these new grains at the expense of the deformed structure. The TNTZO alloy behaves a very similar way to traditional bcc metals in the features of the microstructure,texture and recrystallization.
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 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 a pronounced （110） fiber texture in the axial direction. The recrystallization of the TNTZO alloy is achieved by the nucleation of new grains and the growth of these new grains at the expense of the deformed structure. The TNTZO alloy behaves a very similar way to traditional bcc metals in the features of the microstructure, texture and recrystallization.
