high purity tantalum Texture evolution of high purity tantalum under different rolling.
Tantalum (Ta) is a body-centered cubic (BCC) metal with a very high melting point (2996 °C) and high density (16.7 g/cm3). Due to unique properties, Ta and its ...
Texture evolution in Ta under two different rolling paths is investigated.
•Changing the rolling path has a significant effect on deformation texture evolution.
•Clock rolling leads to more homogeneous microstructure and texture after recrystallization.
•{0 0 1} grains seem to have the ability to nucleate after clock rolling.
Deformation behavior and texture evolution of the material can be significantly affected by strain path change.
For this reason, two rolling methods, unidirectional rolling (UR) and clock rolling (CR), were employed to manufacture tantalum plates.
Texture evolution during unidirectional rolling and clock rolling was studied respectively by orientation distribution function (ODF).
Related annealed microstructures were investigated by an orientation image map (OIM).
Usually, unidirectional rolling led to a strengthening of the main texture component with increasing strain, but for tantalum dominant texture component {0 0 1} θ-fiber was stable after 70% deformation, while minor texture component {1 1 1} γ-fiber was enhanced with increasing strain.
In clock rolling, both of the two fibers were not stable anymore for their intensity varied with the rolling pass.
After the final deformation, a similar texture was produced by the two rolling methods.
However, the recrystallization texture revealed a big difference.
Such different texture development was contributed to microstructural change resulted from rolling path change.
