AbstractIntergranular residual stresses (IS) are microscopic residual stresses which have been found to accumulate along the 〈100〉 direction in steels. The 〈100〉 direction is also the magnetic easy axis direction in steel. This work involved Magnetic Barkhausen Noise (MBN) studies on steel samples, deformed uniaxially to increasing levels of strain. The MBN results indicated that a bulk magnetic easy axis was produced by the deformation process, and neutron diffraction experiments showed that this easy axis was correlated with the tensile strain in grains oriented in the 〈100〉 direction.
