Study of Severe Plastic Deformation by Torsion Test

Abstract

High Torsion Pressure (HPT) is an advanced tool for inducing very significant grain refinement in a wide range of metals. In this research were studied parameters of severe plastic deformation using the torsion test. The material used in this research was a polycrystalline Cu-Al-Ni alloy. For inducing in this material an ultrafine grain structure the thermo mechanical parameters were determined.
