On Shear Nucleation Sites at Phase Transformations in Steel

Abstract: Донской государственный технический университет (344000, Россия, г. Ростов-на-Дону, площадь Гагарина, 1) Аннотация. Рассматривается вопрос о местах зарождения при фазовых переходах, который, даже для такой широко исследуемой области, как мартенситные превращения, остается актуальным. Обсуждается универсальный характер сдвигового зарождения и места зарождения при диффузионных (нормальных) и мартенситных превращениях. Особенности зарождения изучались с помощью наблюдения поверхностного рельефа на сталях 30ХГСА, … Show more

“…Dispersity of the martensite structure was evaluated visually on technical iron samples, as well as statistically [10][11][12] on microsections and thin foils of steel C45, 100CrMn6 and 30HGSA using light (ES METAM RV-22) and electronic (EMMA-4) microscopes by measuring the specific surface [10] and studying the parameters of the surface relief caused by shear transformation [13][14][15][16][17][18][19]. The relief of the martensitic surface was studied using an MII-4M interferometer.…”

“…It can be seen that with an increase in the tempering temperature, the value of the CPD decreases. [19][20][21][22] has a CPD greater than tempering martensite, tempering troostite, and perlite-cementite structure (Fig. 5).…”

“…Both of these deformation processes take place with the participation of dislocations. The problem of describing the martensitic embryo formation mechanism was not posed, since there are a large number of scientific works on this subject [2][3][4][5][6][7][8][9]. One thing is clear that dislocations play an essential role in most theories.…”
