Ultrafine grain structures are being studied worldwide using different types of processes on various materials including low carbon steels. According to state-of-the-art literature equal channel angular pressing (ECAP) and powder metallurgy techniques can truly produce ultrafine to nanocrystalline materials. Unfortunately these techniques do not seem very promising with regard to industrial implementation, because it is not possible to apply these methods in a continuous process. A technique which is based on thermo-mechanical processes of a continuous nature would be much more attractive in terms of industrial upscaling. In the present approach a severe plastic deformation is applied to an interstitial free steel by submitting the material to a severe rolling reduction. In a previous work by the present authors it was already shown that conventional severe rolling reduction, of 95 % (ϵ = 3.0), does not produce a random high angle grain boundary distribution in the deformed sheet. In order to obtain rolling reductions of more than 99 % the Accumulated Roll Bonding (ARB) technique was employed. The microstructure, texture and misorientation distribution of ARB samples which were warm rolled between 500 and 680 °C to a total reduction of 99.9 % (true strain ϵ = 6.9) is studied.
