“…According to the four-component scheme (paradigm) for the study and creation of materials developed by G. V. Samsonov [4,5], the properties of the materials and articles produced from powders are determined not only by the chemical composition and technologies, but also by the type of packing of the particles, their modal dimension, and the specific surface of the powder.…”

“…Using experimental values of the distribution density of the volumes of the particles and the discrete value (2), the distribution density for any powder material may be found. Since (2) contains four unknown constants (a, b, c, d), it is necessary to compile a system of four equations: (4) where Y max is the maximal distribution density; z m , the mode; and z me , the median. Solutions of the system (4) for powders of tungsten carbide-based hard alloys are presented in Table 2.…”

666.76The granulometric characteristics of hard-alloy powders are investigated on an Analysette 22 laser diffraction microanalyzer. Data on the instrument's protocols are tested by a new method developed by the authors and are displayed as formalized distribution densities.There is no need to attempt to assess the critical importance of studies associated with arriving at a more profound understanding of the chemical [1] and statistical [2, 3] characteristics of such loosely dispersed systems as refractory powder materials. According to the four-component scheme (paradigm) for the study and creation of materials developed by G. V. Samsonov [4,5], the properties of the materials and articles produced from powders are determined not only by the chemical composition and technologies, but also by the type of packing of the particles, their modal dimension, and the specific surface of the powder.Refractory powders, a subject we will be speaking of below, were preliminarily investigated on an Analysette 22 laser diffraction microanalyzer. The data of the protocols were then processed according to a technique developed by the present author [6] in order to replace the histograms of the powders by formalized distribution densities. As an example, the histogram for powder of the hard alloy VK8-5 (92% WC + 8% Co) is presented in Fig.

The study analyzes the specifics of modern metal processing technologies. The results of laboratory research for samples made from structural steel St3 with various heat treatment are presented. The results of mechanical tests, measurements of the relaxation coercive field force are shown. The processes that occur with the structure during heat treatment are studied and described. It is made by x-ray diffractograms and images obtained with raster electron and optical microscopes. The influence of structural changes on the relaxation coercive field force and mechanical parameters is described.
