TEM analysis of permanent lattice defects created by forward and reverse martensitic transformations proceeding under stress in nanocrystalline NiTi wire
Original language description
The origin of cyclic instability of stress-strain-temperature responses of NiTi shape memory alloy (SMA) in cyclic thermomechanical loads (functional fatigue) represents one of the unsolved problems in the SMA field. In particular, the mechanism by which incremental plastic strains and permanent lattice defects are generated during thermomechanical cycling is not known. To reveal it, we evaluated recoverable strain, plastic strain and permanent lattice defects in austenite created by forward and reverse martensitic transformations (MT) proceeding under wide range of external tensile stress by closed loop thermal cycling under constant stress and transmission electron microscopy (TEM) analysis of permanent lattice defects in austenite consisting of slip dislocations and deformation bands, variation of crystal lattice orientation and elastic strain field in grains.
