N2 - Effects of annealing on the martensitic and magnetic transitions in Ni 51Ga27Fe22 shape memory alloy were investigated. Curie temperature of the annealed sample decreased with increasing annealing temperature, related to degree of the L21 order, SL21 Both martensitic starting Ms and the austenitic finishing Af temperatures increased with increasing annealing temperature and showed maxima by annealing at 873 K. The Ms and Af seemed to be affected by not only SL21, but also by this magnetic behavior.
