Evolution of Through-Thickness Texture Gradients in Rolled Sheet Products

摘要

The paper reviews recent experimental results on the formation of through- thickness texture gradients during non-uniform rolling and, in particular, addresses their materials-dependence. For that purpose, two different materials (Cu and a low carbon steel) were subjected to non-uniform deformation by cold rolling without application of a lubricant. The effects of the different local strain states through the sheet thickness on microstructure and crystallographic texture were studied by X-ray texture analysis and microstructure observations and compared to results obtained in uniformly deformed sheets.
