Abstract
Results of in-situ neutron diffraction studies of the B2
R
transformation and R-phase reorientation processes in thermal, mechanical
and thermomechanical loads on NiTi alloy polycrystals are presented.
It is discussed how the crystallographic features and structure
instability of R-phase affects the macroscopic thermomechanical
response of NiTi when the R-phase is involved.
