Using molecular dynamics simulations, we study the solid-solid phase transitions induced by strain in Fe nanowires. These show an intricate dependence on the crystallographic orientation of the wire. ⟨001⟩ oriented nanowires exhibit a bcc→fcc transition and preferably follow the Nishiyama–Wassermann path. In ⟨011⟩ and ⟨111⟩ oriented nanowires the transformation is bcc→hcp and proceeds according to the Burgers path. Additionally we show that it is possible to obtain multiple phase transitions accompanied with reorientations.
