Аннотация

Versions are provided for α-martensite rod-shaped crystal initiation by three orthogonal longitudinal elastic waves propagating in orthogonal directions of the types 〈001〉γ and 〈110〉γ in Fe – 31% Ni single crystals. The probability is considered of direct initiation by Bain-type deformation waves. It is demonstrated within the scope of dynamic theory that the anticipated orientation of rod-like crystals is close to 〈111〉γ or to 〈905〉γ. Possible features of martensite crystal tetragonality are discussed. Ultrasound source power required for initiating martensitic transformation is determined.
