Studies of the R-phase transformation in a Ti-51at.%Ni alloy by transmission electron microscopy
D. StrózUniversity of Silesia, Bankowa 12, 40-007 Katowice, Poland
Abstract
The R-phase transformation in a Ti-51at.%Ni shape memory alloy was studied by transmission electron microscopy (TEM) including
high resolution microscopy and in situ observations at cooling. The incommensurability of the superlattice reflections was
examined by recording the diffraction patterns with the use of a CCD slowscan camera and analysing the reflection positions
by DigitalMicrograph program. It is shown that the incommensurability exists in this alloy within a wide temperature range
and its is neither regular nor periodic. It decreases with decreasing temperature reaching finally the commensurate R-phase
state.
