Direct martensitic transformations of low-carbon steels
The proposed model is based on the use of the principle of detailed equilibrium, which occurs during phase transitions of the crystal lattice. This theory complements the theory of Landau phase transitions in crystalline media, as well as the theory of crystallization of matter by Kolmogorov and Avr...

Запропонована модель базується на використанні принципу детальної рівноваги, яка виникає при фазових переходах кристалічної решітки. Теорія доповнює теорію фазових переходів Ландау в кристалічних середовищах і теорію кристалізації речовини Колмогорова і Аврамі. У запропонованій теорії мартенситні перетворення описуються рівняннями індукованих переходів між двома енергетичними рівнями, які відповідають кількості частинок вихідної фази з низькою енергією (аустеніт) і кількості частинок трансформованої фази з більшою енергією (мартенсит). Джерелом перетворень є фонони, кількість яких пов’язана з індукованими переходами частинок між енергетичними рівнями і залежить від температури перетворення. Висновки кількісно відповідають експериментальним даним для перетворень низьковуглецевих сталей. 2023 Article Direct martensitic transformations of low-carbon steels / D.G. Belykh, S.F.
