High-pressure torsion (HPT) is currently considered as one of the most popular severe plastic deformation (SPD) techniques mainly because of the reports of Valiev and his co-workers in Ufa in 1988 on the effectiveness of the method in creating submicrometer grains with principally high misorientation angles. The HPT method was first introduced in 1935 by Bridgman at Harvard University and applied to many different kinds of metallic and non-metallic materials. The method has been employed not only as a SPD process in metallurgy, but also as an important scientific tool in many different fields of science and engineering (physics, chemistry, geology, biology, materials science, and tribology). This talk reviews the main results achieved between 1935 to 1988 and explains their importance in advancement of materials and methods.
