## Title

- title: Grain size dependence of <hkl> intergranular lattice strain generated by
    plastic deformation in ferritic steel
  title_type: original
  lang: en

## Description

- description: The uniaxial deformation behavior of low-carbon ferritic steels with
    grain sizes of 0.47 μm and 1.5 μm was investigated using in situ neutron diffraction
    measurements under both tensile and compressive loading. The analysis focused
    on the evolution of <hkl> lattice (elastic) strains, originating from anisotropy
    in <hkl> elastic moduli and differences in plastic flow among grains. Such plastic
    strain incompatibilities produce <hkl> intergranular lattice strains (or stresses).
    The experiments revealed substantial residual <hkl> intergranular lattice strains
    following both tensile and compressive plastic deformation. Transmission electron
    microscopy confirmed the grain-size dependence of dislocation structures formed
    during plastic flow, suggesting that plastic relaxation near grain boundaries
    becomes increasingly constrained with grain refinement. Overall, the results demonstrate
    that the magnitude of residual <hkl> intergranular lattice strains increases as
    grain size decreases from several tens of micrometers down to 0.5 μm.
