摘要：
A single-phase wide-hysteresis shape memory alloy Ni50Mn25Ga17Cu8 is reported. This alloy undergoes martensitic transformation at 264 degrees C, and has transformation hysteresis of 40.4 degrees C, shape memory effect of 6.2%, compressive plasticity of 22%, and compressive strength of 878 MPa. The transformation hysteresis is further expanded by deformation in the martensite state. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
