On the evolution and modelling of Cube texture during dynamic recrystallisation of Ni–30Fe–Nb–C model alloy

Journal Article


Abstract


  • A combination of electron back–scattering diffraction and visco–plastic self–consistent (VPSC) –based dynamic recrystallisation (DRX) modelling was used to investigate the texture evolution in a Ni–30Fe–Nb–C model alloy subjected to hot plane strain compression to a true strain of 1.2 at temperatures of 925 °C and 1075 °C. Typical of hot rolled face centred cubic materials (in the absence of DRX), deformation at 925 °C led to the development of β–fibre orientations along with a weaker Cube ({001}〈100〉) component. This Cube orientation intensifies and dominates the final texture with the occurrence of DRX during deformation at 1075 °C. The VPSC model successfully predicted the experimental textures at 925 °C (without DRX) and 1075 °C (with DRX), by accounting for non–octahedral {011}〈110〉 slip activity at high temperatures and by using a physically more realistic grain–matrix interaction scheme intermediate between the Taylor and Sachs models. Our simulations show that the dominance of the Cube orientation in the DRX texture at 1075 °C can be ascribed to its higher stored energy and subsequently higher probability of nucleation, combined with its stabilisation due to the activation of non–octahedral {011}〈110〉 slip.
