A device was designed to apply the DirectionalRecrystallization method to Fe-based alloys in order to obtain bamboo-likemicrostructures. This microstructure is suitable for improving creep propertiesand resistance to fatigue in some alloys and for enhancing pseudoelasticproperties in shape memory alloys. The design and construction of a flat coilis described in detail. In addition, we developed an electromechanical systemto control the movement of a wire within the flat coil. The constructiondetails and system performance are presented. Furthermore, metallographicstudies taken from the directionally recrystallized low-carbon steel samplesare shown. Nearly monocrystalline and bamboo-like microstructures were achievedin the steel wires.
