High-temperature shape memory alloys
From fundamental insight to application
High-temperature shape memory alloys (HT-SMA) exhibit a shape memory effect above 100?C and are very attractive for applications in engineering, aviation and automobile industry. Recently, the Ti-Ta system has been shown to be a promising candidate for a new class of HT-SMAs.
Within the DFG research unit FOR1766 fundamental insight into and characterisation of HT-SMAs is achieved through a close collaboration of experimental and theoretical projects. A particular focus will be on the Co-Ni-X system (pseudo-elasticity) and Ti-Ta-X system (actuators). The research unit involves projects at the Leibniz University Hannover, the Ludwig Maximilian University Munich as well as at the Institute for Materials (RUB) and at ICAMS (RUB).
