Texture Evolution in Aluminum Alloy Sheets During Uniaxial Tension

摘要

The texture evolution during uniaxial tension inAA3003 sheet with inhomogeneous texture through thicknessdirection was investigated. To analyze the texture evolution,incomplete pole figures were measured and analyzed usingWIMV method. After uniaxial tension along RD, copper, Goss,P, cube components increased and along TD, rotated copper,cube and Es components increased. Texture evolved towards the<100> and <111> type fiber textures after uniaxial tensiledeformation, The stable orientations during uniaxial tensioncould be predicted from the lattice rotation field with the ratesensitive model. Plastic strain ratio was measured and comparedwith the calculated value.
