Texture Analysis and Anisotropic Properties of a Rolled CuZn36 Brass Alloy

摘要

In this study, the mechanical properties of an annealed CuZn36 rolled brass alloy with 0.2 mm thickness with respect to anisotropy expressed in terms of plastic strain ratio measurements (r-values, normal and planar anisotropy) are related with the development of specific rolling and recrystallization texture components obtained by EBSD. Anisotropic behaviour is primarily controlled by the crystallographic texture and constitutes an indicator of multi-axial mechanical behaviour, affecting directly the drawability and sheet metal formability. Microstructure examination employing optical and Scanning Electron Microscopy of tensile specimens are performed in order to investigate the emergent damage mechanisms in relation to the texture and structure evolution of the final product.
