Notes:
NiAl shape memory alloy thin films have been fabricated by a solid-state reaction inAl/Ni bilayer films. Two kinds of synthesis have been used. The first one consists in heating anAl/Ni bilayer film system to temperatures above 480 K. The second one implies the successivedeposition of nickel and aluminum films onto a substrate with a temperature above 480 K.Regardless of a kind of the solid-state synthesis, the films obtained reveal a two-way shape memoryeffect. It is supposed that the solid-state reaction in Al/Ni bilayers starts at a temperature AS of thereverse of the martensitic transition in NiAl alloy. This indicates that the NiAl shape memory alloythin films can be formed directly during the synthesis without need for lengthy heat treatment
