“…A round bar cast sample with dimensions 4 mm × 1 m was produced in each casting operation. The details of the OCC process can be found in the previous literatures reported by Soda et al (1995). The mechanical properties of the OCC Al alloy were compared to those for the same Al alloy made by conventional gravity casting.…”

Throughout a long and distinguished career, the research activities conducted by Professor Ravindran have been characterized by the quest to generate fundamental as well as practical knowledge through collaborative efforts involving academia and industry as a basis for development of innovative manufacturing routes and improvement in performance of existing products and processes based on near-net-shape casting technologies. In this paper, the generation, validation, and implementation of new knowledge is illustrated by the Ohno Continuous Casting process, a heated mold system that permits the production of net-shape or near-net-shape products with a high-quality surface, controlled solidification structure, and significantly enhanced properties.

“…Therefore, many researchers have reported that the axial crystallographic direction of single crystal produced by OCC technique is closely parallel to 100 [3,4]. However, Soda et al [5] have found that the casting speed affects axial crystallographic orientation of single crystal copper wire and proved that single crystal with other orientations, such as 110, 111 and so on, can be obtained by OCC. Now that the single crystal with different initial orientations can be produced by OCC, it is necessary, therefore, to systematically investigate the effect of initial orientation on the microstructure and texture of drawn single crystal copper wires.…”

By means of electron backscattering diffraction and transmission electron microscopy the microstructure and texture of drawn single crystal copper with initial orientation 110 parallel to axial direction have been investigated in the present work. In order to analyze the effect of initial orientation on microstructure and texture of drawn copper, the results of the drawn 110 single crystal copper wires have been compared with 100 and 111 single crystal copper wires. It is found that the grain subdivision of 110 single crystal is more evident than that of 100 and 111, and the textures consisting of 111 and 100 abruptly form in the drawn 110 single crystal. At high strains, due to shear strain, the distribution of fiber textures is imhomogenous along the radial direction of drawn 110 single crystal copper wires. 100 is near the surface and 111 is at the center. The microstructure results of drawn 110 single crystal show that at low strains, it can be characterized as two kinds of geometrically necessary boundaries with noncrystalline character. At medium strains, S bands can be observed. At high strains, lamellar boundaries form. Mean misorientation and average spacing of dislocation boundary are larger in drawn 110 single crystal, as compared with 111 and 100. In drawn 110 single crystal with high strains, the bimodal distribution forms at lower strains than in drawn 100 single crystal, which is because the dislocation boundaries with high angle are contributed by not only the boundary between 111 and 100 fiber textures but also the boundary in 111 or 100 texture. single crystal copper, cold drawing, texture, microstructure Citation: Chen J, Yan W, Li B, et al.
