摘要：

Effects of annealing on the martensitic and magnetic transitions in Ni51Ga27Fe22 shape memory alloy were investigated. Curie temperature of the annealed sample decreased with increasing annealing temperature, related to degree of the L2(1) order, S-L21. Both martensitic starting M-s and the austenitic finishing A(f) temperatures increased with increasing annealing temperature and showed maxima by annealing at 873 K. The M-s and A(f) seemed to be affected by not only S-L21, but also by this magnetic behavior. (C) 2003 Elsevier B.V. All rights reserved.
