Description of habit planes in wave models of martensite growth. Habits (225), (557), AND (925)
The habit planes of the systems Fe-Ni and Fe-C are described in a two-wave scheme. The longitudinal wave in the direction of the Δ axis with fourfold symmetry is chosen as one of the wave pairs in describing all habits. Then, the second quasilongitudinal wave for each of the habits is found uniquely. In particular, it is shown that for ratios of longitudinal wave velocities 1 > VΣV Δ -1 > 1.3 (Σ is the twofold symmetry axis), formation of (557) habits is most probably, while for 1.3 > VΣV Δ -1 , the formation of (225) habits is most probable.
