| The present invention relates to a torsional extreme-plastic processing method. In other words, a processing method in which severe plastic deformation based on torsion and compressive force is applied to a material by using a mold to produce miniaturize and nano-size crystal particles in a conic pipe. According to the severe plastic deformation method of the present invention, a punch that matches an inner shape of the conic metal pipe is mounted inside the conic metal pipe, and then a mold that matches an outer shape of the conic metal pipe is mounted outside the conic metal pipe. Thus, microstructures of the conic metal pipe may be ultra-finely crystallized or nano-crystallized through shearing by applying compression and torsion to the conic metal pipe. | ||||||
