Interpretation of some characteristic morphological signs of Fe-Ni and Fe-C martensite in phonon maser model

On the basis of limitations, placed on electron spectrum by the conditions of generation of lattice shifts waves, directions of quasilongitudinal waves near the symmetry axes of the second and fourth orders of fcc phase are singled out. In the wave scheme the following notions are interpreted: habitus planes, the rule of habitus comparison (orientational triangle) with the direction of compression and tension of strain, twinning plane, the ratio of fine and macrostructures, regularity of crystal grouping of packet martensite. Criteria for habitus plane chanae and orientation effect in the external magnetic field
