Pearlite is composed of ferrite and cementite with different strength. In addition, flow stress is different from grain to grain in the ferrite matrix depending on crystal orientation. In previous reports, our group reported the stress partitioning behavior and influences of cementite volume faction and texture. In this study, we examined stress partitioning behavior during tensile deformation by means of in situ neutron diffraction for pearlitic steels with different interlamellar spacing. As a result, it is concluded that the yield strength of ferrite matrix is affected by interlamellar spacing.
