The microstructure and texture of torsion-reverse torsion experiments. [Al-1Mg]

PDF Version Also Available for Download.

Description

Recent experiments with short thin-walled tubes (Lindholm design) tested in torsion and reverse torsion have confirmed both the persistence of a shear texture at zero net strain and the restoration of the grain shape. Calculations of theoretical texture development using a code based on the Bishop and Hill analysis have confirmed the reversibility of texture development when Taylor-based models are used. This code includes the effect or Relaxed Constraints and uses a nonlinear strain rate sensitivity to resolve the ambiguity of slip system choice. Calculations performed with the Asaro-Needleman code do leave a small residual texture at zero net strain. ... continued below

Description

Recent experiments with short thin-walled tubes (Lindholm design) tested in torsion and reverse torsion have confirmed both the persistence of a shear texture at zero net strain and the restoration of the grain shape. Calculations of theoretical texture development using a code based on the Bishop and Hill analysis have confirmed the reversibility of texture development when Taylor-based models are used. This code includes the effect or Relaxed Constraints and uses a nonlinear strain rate sensitivity to resolve the ambiguity of slip system choice. Calculations performed with the Asaro-Needleman code do leave a small residual texture at zero net strain. The conclusion is that there is sometimes an irreversible component of texture development that is not accounted for by the geometry of plastic deformation. 11 refs., 6 figs.
