The effect of two stage deformation on ferrite transformation has been investigated by in situ neutron diffraction. Deformation induced ferrite transformation was found not only in the first stage compression but also in the secondary compression. The secondary compression was found to accelerate ferrite transformation even after the first compression effect disappeared. During the secondary compression, ferrite (110) diffraction intensity decreased by the evolution of compression texture of ferrite, while the integrated diffraction intensity of ferrite (110) was increased due to accelerated ferrite transformation. Hence, multi-stage or continuous deformation must be very effective to promote ferrite transformation.
