ОПИСАНИЕ МОРФОЛОГИЧЕСКИХ ПРИЗНАКОВ ПРИ B2→B19 МАРТЕНСИТНОМ ПРЕВРАЩЕНИИ В РАМКАХ КОНЦЕПЦИИ УПРАВЛЯЮЩЕГО ВОЛНОВОГО ПРОЦЕССА

The paper analyzes the possibility of describing of morphological characters in В2→В19 transformation in the framework of dynamic theory based on the concepts of heterogeneous nucleation and wave growth of martensite crystals. On the example of Ti-Ni-Cu alloys it is shown that the predicted and observed orientations of habit planes agree well. The issue that strain relations remain valid in going form thresholds to final values is considered and calculation results for orientation relations and conditions of their realization are discussed.
