The Bauschinger effect in drawn and annealed nanocomposite Cu–Nb wires

To compliment recent diffraction based measurements of the internal stresses in heavily co-deformed Cu–Nb nanocomposite wires, Bauschinger tests have been performed and used to interpret bulk mechanical response. The role of microstructural heterogeneity has been highlighted and a Masing-type model developed to predict both forward and reverse Bauschinger behaviour. This model has been compared to recent physically based models that are used to …
