HTSMA

Materials

Focus will be on Co-Ni-X (X = Al, Ga, ...) and Ti-Ta-X (X = Al, Sn, Bi, ...) alloys. The Co-Ni-X system is interesting as it already provides for stable high-temperature pseudoelasticity at temperature of up to 200 °C. Components with pseudoelastic behavior could be used for damping in various applications. By contrast, Ti-Ta-X is of interest for actuators as these alloys can show shape memory at elevated temperatures.  

Based on previous studies, both alloy systems are promising candidates. However, the relevant microstructural processes that control functional degradation at elevated temperatures are not clear yet.
