Abstract
Two-way shape memory effect of sputter-deposited Ti-rich Ti-Ni alloy films was investigated. Amorphous films of Ti-48.6at.% Ni alloy obtained by sputt ering were crystallized by holding at 743 K for 0.3 ks and then aged under constraint (circular shape) at the same temperature for 1.8 ks. On these sp ecimens, observation of spontaneous shape change during cooling and heating , and also differential scanning calorimetry (DSC) were done. The aged film s showed two-way shape memory effect in association with the B2 <---->R <-- --> B19' transformation. (C) 2001 Elsevier Science B.V. All rights reserved .
