SFB459 » Shape Memory Technology - Fundamentals, Design, Manufacturing (2000 - 2012)


SFB459 has strongly influenced both research and teaching at our Chair and at the Institute for Materials. We have been able to make a name for ourselves in this fascinating area of research, achieving conspicuous visibility throughout the world, both in terms of basic research as well as in manufacturing and applications.

We were able to greatly improve the experimental infrastructure of our Chair and of our Institute for Materials in the fields of electron microscope, ingot metallurgy and the mechanical testing of materials. In addition, a whole series of new research groups were established within the orbit of SFB459. We are in close contact with many leading research groups in the field of shape memory technology and will continue in future to vigorously conduct research in this area.

As part of the SFB459 project, we have been able to make significant contributions, across many diverse fields, to a clearer understanding of materials science. We proposed a new method for producing highly pure NiTi alloys. We deciphered how precipitates affect the martensitic transformation, we gained new insights into the nature of the interaction between dislocation plasticity and the martensitic transformation and in particular we can now explain the elementary processes that determine the structural and functional fatigue of shape memory alloys.
