KINETICS OF SOLID-PHASE INTERACTION BETWEEN DISSIMILAR CRYSTALLINE MATERIALS UNDER AN APPLIED LOAD IN A WIDE TEMPERATURE RANGE
Main Article Content
Abstract
In the paper, a functional dependence of the kinetics of plastic strain and the change in shape of copper microprotrusions under the action of an applied load in a wide temperature range was obtained. The equations obtained in the paper can further find wide practical application for calculating the microstresses of the 2nd kind arising at the interface of a metal - an inorganic material (for example, iron carbide, oxides, nitrides, etc.) during plastic strain, and will also allow estimating the intensity of the processes of the first stage of a solid-phase topochemical reaction between dissimilar crystalline materials with sharply different creep resistance, leading to the formation of a real and physical contact between the surfaces. Synthetic monocrystalline corundum was chosen as such a response material in the paper.
