Annotation
SIn-situ tensile straining of tetragonal martensite of Ni-Mn-Ga alloy was studied in a transmission electron microscope. Before straining, the martensitic structure of the samples consisted of thermally induced self-accommodated multi-variants. During the in-situ straining, detwinning processes were recorded. The movement of the twin boundaries was followed in detail. The detwinning processes occurred by movement of twinning dislocations emitted from interfaces between two twinned bands.
