When plastic deformation is given to pearlite steel, misfit strain generates between cementite and ferrite. Even in the ferrite matrix, stress is different from grain to grain depending on the crystal orientation. This "block stress" stems from the heterogeneous plastic flow among differently oriented blocks and must be influenced by texture. In this study, therefore, in situ neutron diffraction under tensile deformation for as-patented pearlite steels with weak texture were conducted in order to estimate the strength anisotropy in the crystal orientation of ferrite blocks. Consequently, it was found that (110) and (211) ferrite family blocks in the pearlite steels are harder than (200) ferrite family ones.
