文摘
- •
A novel rolling schedule, 135° clock rolling, was presented in this paper.
- •
The orientation dependence in tantalum was alleviated by changing rolling paths sequentially with a rotation angle of 135°.
- •
The substructural evolutions of θ-fiber and γ-fiber grains under unidirectional and 135° clock rolling were analyzed.
- •
The orientation-dependent stored energy was analyzed in a quantitative way.
