英文摘要	The aim of this study is to investigate the microstructure martensitic transformation behavior shape memory effect and superelastic property of N1(45) 1Cu5Cr0 3 alloy with Cu and Cr substituting for Ni After annealing the alloy showed single step A-M/M-A transformations within the whole annealing temperature range of 623 K to 1273 K even in the presence and 112(Ni Cu) precipitates With the increase of the annealing temperature the transformation temperatures exhibited three stages increasing from 623 K to 873 K decreasing from 873 K to 1023 K and unchanging from 1023 K to 1273 K Meanwhile the critical stress for stress Induced martensitic (SIM) transformation decreased to a minimum value and increased after that exhibiting a V shape curve The alloy annealed at 623 773 and 923 K exhibited shape recovery ratio more than 90% when the deformation strain was below 20% (C) 2010 Elsevier B V All rights reserved; Materials Science, Multidisciplinary; Physics, Applied; SCI(E); EI; 7; ARTICLE; 1; 74-77; 65
