Abstract: Nanocrystalline martensitic materials can show the shape memory effect and superelasticity in combination with exceptional strength. The in-depth knowledge of the mechanisms of martensitic phase transformations of these materials is a prerequisite for controlling their functional properties. Direct structural observations on the nanoscale are expected to give substantial insight in these complex physical mechanisms.
