摘要：

It is shown that the mechanical and shape memory characteristics of the polycrystalline Ni54Mn25Ga21 high temperature shape memory alloys can be improved by grain refinement. The maximum shape memory strain is 4.2%, and the compressive plasticity is higher than 10%. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
