Dynamic Model of the Formation of an Intermediate Mesorcopic State During B2 → B19 Martensitic Transformation

Formation of martensite crystals in the limiting case of a supersonic growth rate

“…We also hope that we have managed to set forth the concepts that transparently disclose the physical nature of the limiting case of martensite crystals' supersonic formation, and attract attention to a number of tasks for initiation of new investigations in the topical thematic area of martensitic and bainitic transformations. Currently, the dynamic theory is actively developing, finding a successful application in all the above-mentioned areas (see, e.g., [43][44][45][46][47][48][49][50][51]). It is useful to bear in mind that in the methodological aspect this review should be viewed as mutually complementary with the reviews [52] and [53].…”

Morphological features in B2→B19 martensitic transformation and their description based on the concept of controlling wave process

“…Using the approximation of longitudinal waves (at low deviations of wave vectors from the symmetry axes), we may introduce the notion of an intermediate state that rapidly arises in the wave mode [18,19]; transition to this state is associated with the achievement of the most part of final strains upon the fulfilment of Eq. (3).…”

“…The choice of a particular plane is governed by additional considerations, first of all, by the information (even hypothetical) about the cooperative rearrangement mechanism. Particularly, the choice of elementary cells in the form of rectangular parallelepipeds allows relations (18) to be considered as an expected variant. An important issue in the study of thin films and foils is the degree of constraint imposed on the relaxation conditions of the lattice after stability loss.…”

“…The above remarks suggest that a particular variant of Eq. (18), which reflects the choice of elementary cells in .igs. 1a and 1b, can be easily compared to a particular variant of Eqs.…”

“…A significant role in PHYSICAL MESOMECHANICS Vol. 18 No. 3 2015 the choice of an instability channel is attributed to intermediate slip systems that introduce short-wave modulation to the initial B2 lattice, i.e., it is assumed that transformation actually occurs in a premodified B2 phase.…”
