Abstract
The α↔γ allotropic transformation in vapor deposited thin foil of pure iron is investigated by in-situ transmission electron microscopy. The α↔γ transformation proceeds by following Bain's orientation relationship, which is {001}γ∥{001}α and 〈001〉γ∥〈011〉α, indicating that the α↔γ transformation is martensitic in nature. No eminent dislocation is introduced within the newly transformed α- or γ-iron grains. The grain size of the re-transformed α-iron from the γ-iron becomes extremely larger than that before α↔γ transformation.
