Bend it, shape it, remember it: Shape-memory alloys have the useful property of returning to their original shape after being greatly deformed. This process depends on the collective behavior of many small mineral grains in the metal. Using three-dimensional x-ray diffraction, Sedmák et al. tracked over 15,000 grains in a nickel-titanium shape-memory alloy as it moved through this transformation, thus linking microscopic changes to the bulk deformation.

About Me

Since 1991, I have been involved in the research of martensitic transformations and related phenomena in solids and functional materials, particularly Shape Memory Alloys /SMA/, focusing on the following: Experiments and modelling of martensitic transformations in Cu-based alloy single crystals; Experiments and modelling of thermomechanical behavior of SMAs under general loading conditions; Development, testing and modelling of NiTi-reinforced composites; Analysis of physical property changes of solids associated with martensitic transformation; Thin NiTi filament research; Development of SMA textile technologies; Development and application of thermomechanical models of SMAs; In situ X-ray and neutron diffraction applied to SMAs.
