Abstract
Pearlite is composed of ferrite and cementite with different strengths. Even in the ferrite matrix, stress must be different from grain to grain depending on the crystal orientation which is called block stress. The ferrite block stress and phase stress in two pearlite steels with a strong ‹110› fiber texture or a weak texture were studied by using a time of flight method of in situ neutron diffraction during tensile deformation. It is found that the texture influences the block stress particularly in the transverse direction.
