Abstract:
The crystallographic texture and formability of aluminium alloy 5086 annealed at 160, 200, 250 and 300°C have been studied. Experimentally determined forming limit diagrams (FLDs) for the above said Al 5086 sheets, their crystallographic textures and their orientation distribution function plots made by X-ray diffraction were analysed. The present study shows a comparison between these FLDs of Al 5086 sheets and the corresponding result of crystallographic texture analysis. The FLDs and crystallographic textures were then correlated with normal anisotropy of the sheet metal. It was found that aluminium alloy 5086 annealed at 300°C possessed good formability, preferred texture and high normal anisotropy value.Keywords: FORMING LIMIT DIAGRAM; ALUMINIUM 5086; NORMAL ANISOTROPY; TEXTURE COMPONENTS; CUBE TEXTURE
