Interface Driven Pseudo‐Elasticity in a‐Fe Nanowires
Molecular dynamics simulations of bent [100] α‐Fe nanowires show the nucleation of twins and nanoscale interfaces that lead to pseudo‐elasticity during loading/unloading cycles. The new type of interfaces along {110} stems from the accumulation of individual <111>/{112} twin boundaries and stores high interfacial energies. These nonconventional interfaces provide a large part of the driving force for shape recovery upon unloading, while the minimization of surface energy is no longer the dominant driving force. This new pseudo‐elastic effect is not much affected by surface roughness, and can be extended over a wide range of wire diameters, if the sample is seeded with conventional twin boundaries, which will transform to the desired {110} interfaces under bending.
