Abstract
Principles of the physical simulation of conditions at the initial stage of γ-α martensitic transformation are formulated on the basis of the theory which synthesizes conceptions of the heterogeneous nucleation and the wave growth of martensite. The choice of the experimental method available to realize the artificial initiation of transformation is justified. Possible mechanisms of excitation of the hypersonic controlling waves by a single supershort laser pulse are presented. The information about perspectives of using the received results for alloys featuring the shape-memory effect is also presented.
