Abstract

In this work the microstructure, texture and mechanical properties during different stages of reverse cold rolling (RCR) process on aluminium alloy AA1100-H14 were analysed.  Microstructure was observed using optical and electron scanning microscopy. Texture was analysed using X-ray diffraction (macrotexture) and electron back-scattering diffraction (microtexture) techniques. Tensile test and microhardness measurements were carried out. Results showed that a high deformation using RCR was obtained in samples of annealed state leading to maximum values of tensile strength and hardness, along with a reduction of ductility. Intensity of -fibres decreased producing unstable textures {112} <110> while microstructure exhibited refinement of grain, with enlarged morphology.
