Reconstruction of Martensitic Nucleation Process from Morphological Attributes

Abstract
Within the framework of the concepts of heterogeneous nucleation and wave growth of martensite the refinement of a technique of account of wave normals N_w to expected habits planes are carried out. The technique allows to connect orientations of N_w with definite areas of nucleation of crystals in an elastic field of defects. The specific results are presented for system Cu-Zn. As separate rectilinear dislocations with lines [11-1] and dislocation loops basic elements of which are pieces of these lines are considered here as probable centers of nucleation. It is shown, that the spectrum of N_w can be coordinated with experimentally observable space distribution of normals N_e in a vicinity of a pole [2 11 12]. The similar coordination opens additional opportunities to reconstruct a stage of martensite nucleation from morphological attributes and to transform a distribution of habits in the informative parameter.
