Surface-layer microstructure control and bendability of a commercial purity titanium sheet using continuous cyclic bending

Crystallographic Orientation Distribution Control by Means of Continuous Cyclic Bending in a Pure Aluminum Sheet

Continuous cyclic bending (CCB) has been proposed as a useful straining technique to produce the high strain on the surface layers and the lower strain in the central layer of the sheet. A pure aluminum sheet is worked by the CCB using the ‘‘Roll traveling device’’ and ‘‘Roll driven machine’’. It is found that a sharp Cube orientation is formed by the CCB and subsequent annealing in the pure al...

Cyclic deformation behavior of high-purity titanium single crystals: Part II. Microstructure and mechanism

3D reconstruction of microstructure in a commercial purity aluminum

The topic of reconstruction of polycrystalline microstructures is briefly reviewed. An example is given of using orientation maps to reconstruct digital microstructures with a representation of a polycrystal structure that includes crystallographic orientation information. The method uses packing of ellipsoids to approximate the grain structure, coupled with Voronoi tessellation. For the exampl...

Mechanical Strength and Biocompatibility of Ultrafine-Grained Commercial Purity Titanium

The effect of grain refinement of commercial purity titanium by equal channel angular pressing (ECAP) on its mechanical performance and bone tissue regeneration is reported. In vivo studies conducted on New Zealand white rabbits did not show an enhancement of biocompatibility of ECAP-modified titanium found earlier by in vitro testing. However, the observed combination of outstanding mechanical...

Characterization of Microstructure and Bending Response of Sheet Material: Influence of Thickness

Bending process is one of the most significant fields of application of sheet metal die. In bending process, it is quite vital that the product should have the desired angle. Furthermore, in order to obtain the desired angle in the bent parts, spring-go and spring-back amounts must be known. In this study, 30o, 60o and 90o bending processes were applied to S235JR (1.0038) sheet metal having 3, ...
