Abstract
Local changes of the phase transition on a SM one‐way actuator have been investigated by time‐dependent IR thermography and compared with the local behavior of thermal properties studied by means of scanning thermal microscopy and modulated IR radiometry at room temperature and at 120 °C. The results point towards large spatial inhomogeneities of the shape memory properties developing with increasing temperature and which are the reason that only parts of the material transform into the austenite phase.
