Multiscale twin hierarchy in NiMnGa shape memory alloys with Fe and Cu

X-ray microdiffraction and scanning electron microscopy studies reveal 10M martensitic structure with a highly correlated multiscale twin hierarchy organization in NiMnGaFeCu shape memory alloys. High compatibility is found at the twin interfaces resulting in a highly correlated twinned lattice orie...
