摘要：

High-pressure torsion has been successfully applied to polycrystalline Cu-Al-Ni shape memory alloys that had been prepared by a powder metallurgy methodology. The samples before and after high-pressure torsion were characterized by optical and electron microscopy and differential scanning calorimetry. After high-pressure torsion the alloys became ultra-fine grained and the present phases were identified. (C) 2015 The Authors. Published by Elsevier Ltd.
