В работе представлена модель пластической деформации дисперсно-упрочненных сплавов, основанная на уравнениях баланса деформационных линейных и точечных дефектов с учетом их трансформации в процессе деформации и перехода когерентной фазы в процессе деформации в состояние неперерезаемой скользящими дислокациями в зоне сдвига при различных температурах деформации. Проведено исследование влияния упрочняющих частиц, упорядоченных по типу L 12, а также внешних воздействий на деформационное упрочнение гетерофазных сплавов с частицами. В результате моделирования выявлена температурная аномалия механических свойств сплава с ГЦК матрицей и упрочняющими частицами со сверхструктурой L 12.In work the model of plastic deformation of the disperse strengthened alloys based on the equations of balance of deformation linear and dot defects taking into account their transformation in the course of deformation and transition of a coherent phase in the course of deformation is presented to a state not cut by the sliding dislocations in a shift zone at various temperatures of deformation. Research of influence of the strengthening particles ordered on the L 12 type and also the external impacts on deformation hardening of heterophase alloys with particles is conducted. As a result of modeling temperature anomaly of mechanical properties of an alloy with FCC a matrix and the strengthening particles with superstructure of L 12 is revealed.
