- Abstract
-
The article examines ways of solving one of the sides of the problem of active import substitution and diversification of the supply of special materials in connection with the termination of stable cooperative ties with the russian federation. An approach is proposed to analyze the compliance of the characteristics of new materials with the requirements of the current design and technological documentation for materials of the domestic ammunition industry, namely: for the manufacture of projectile cases.
It is substantiated that the most effective and informative methods of researching the microstructural characteristics of metallic materials and justifying the expediency of their use for the production of shell casings are the use of raster electron microscopy and X-ray microanalysis, as well as optical emission and Fourier EPR spectrometry.
The results of the analysis of the physical and chemical characteristics of fragments of 152-mm high-explosive OF-29 high-explosive projectiles made from traditional materials and from materials obtained as a result of import substitution and diversification of supply, which was carried out on the basis of hardware studies using a scanning electron microscope JSM-6490LV, are given with use of INKA Energy 350XT energy dispersive spectrometer, optical emission spectrometer and ELEXIS SERIA E 580-10/12 Fourier EPR spectrometer.
The methods of analysis of physico-chemical properties of metal fragments of artillery shell casings chosen for research allow not only to study the structure and composition of metals, but also to draw conclusions about the nature of the explosion, the properties of the explosive substance and the temperature acting on the shell casing during the explosion. These methods can also be used for research on the influence of the composition and concentration of chemical elements of the explosive substance on the change in the structure of the metal and the fragmentation of the projectile body during the explosion.
