Abstract: In the wave model of martensitic transformations, the influence of the tensile strain on the creation of non-equilibrium electrons is crucial for the principle of wave amplification by stimulated emission of phonons from an inverted electronic population. By consideration of the strain-effect on the electronic energy spectrum it is shown that - for certain interval of finite strain - the density of active electronic non-equilibrium states in a strained lattice can satisfy the conditions for a phonon-maser effect. © 2007 Elsevier B.V.
