Abstract

Despite its significant effect on metal deformation, grain size is not usually considered when modelling the evolution of intergranular stresses. This paper presents an experimental in situ straining neutron diffraction study of deformation in two interstitial free steels with different grain sizes, one with 80 μ m and one with 350 μ m. These were compared against the predictions of crystal plasticity finite element modelling, which is scale insensitive. Only small differences in the evolution of both mean grain family elastic strains and peak width were detected. These were attributed to local texture effects. © 2006 Elsevier B.V.
