| Abstract Scope |
Crystallographic texture of plates and sheets produced by conventional rolling is not uniform through the thickness due to non-uniformity of shear strain distribution induced during rolling. No shear strain is introduced at mid-thickness while shear strain is non-zero elsewhere. Texture non-uniformity through thickness can be eliminated by improving the shear strain distribution. In this paper, a novel asymmetric rolling method, named tilt-rolling, is introduced. Coupling of finite element models (FEM) and crystal plasticity models employed to develop the tilt-rolling process will be explained. Texture results of tantalum plates produced by tilt rolling will be demonstrated. The advantages of tilt-rolling in comparison to other asymmetrical rolling methods such as rolls with different diameters and speeds will be discussed. |
