MACROSCALE PLASTICITY PARAMETER OF METALS AND ALLOYS

DOI: 10.17804/2410-9908.2024.3.064-072

It is shown that plastic flow in solids emerges in a localized manner at a macroscopic scale of ~10−2 m. Localized plastic flow zones form patterns of localized strain, which are the projection of the autowave processes of plastic flow, developing in the bulk of the material, onto the specimen surface under study. The speckle photography method was chosen as a source of information about the kinetics of plastic deformation. A common feature of localized plastic flow in solids is the elastic-plastic invariant of deformation, which combines the typical characteristics of localized plastic flow autowaves with those of elastic waves in a crystal lattice. The invariant ratio is defined for nearly forty various materials (BCC, FCC, and HCP metals and alloys, alkali-halide crystals, ceramics, and rocks) under active tension and compression in a temperature range of 143 to 420 K. The origin of the invariant and its relation to other physical characteristics of the crystal lattice, e.g. the Debye temperature, is discussed in physical terms. Besides, numerous corollaries of the elastoplastic invariant are derived, enabling one to describe adequately the regularities of plastic flow. This, in turn, makes it possible to consider the elastic-plastic invariant of deformation as the main equation of the currently developing autowave approach to the physical theory of plastic deformation.

МАКРОМАСШТАБНЫЙ ПАРАМЕТР ПЛАСТИЧНОСТИ МЕТАЛЛОВ И СПЛАВОВ

Показано, что пластическое течение в твердых телах возникает локализованно
на макроскопическом уровне ~10−2 м. Зоны локализованного пластического течения формируют картины локализованной деформации, представляющие собой проекцию автоволновых процессов пластического течения, развивающихся в объеме материала, на наблюдаемую поверхность образца. В качестве источника информации о кинетике пластической деформации выбран метод спекл-фотографии. Общей особенностью локализованного пластического течения в твердых телах является упругопластический инвариант деформации, сочетающий типичные характеристики автоволн локализованного пластического течения с характеристиками упругих волн в кристаллической решетке. Инвариант определен почти для сорока различных материалов (ОЦК-, ГЦК- и ГПУ-металлов и сплавов с решетками, щелочно-галоидных кристаллов, керамики и горных пород) в условиях активного растяжения и сжатия в интервале температур 143–420 К. С физической точки зрения обсуждается происхождение инварианта и его связь с другими физическими характеристиками кристаллической решетки, в частности с температурой Дебая. Выведены также многочисленные следствия упругопластического инварианта, позволяющие адекватно описывать закономерности пластического течения. Это, в свою очередь, позволяет рассматривать упругопластический инвариант деформирования как основное уравнение развивающегося в настоящее время автоволнового подхода к физической теории пластического деформирования.
